Gotta love the TPI motors

[Hartz]

Let's hear it for TPI motors!

:yay: :2thumbs: :woot:

I can't seem to get away from them.

tuned ports rock my dad has got his to run 8.89 in the 1/8 mile with only shorty headers, holley stealth ram and cut out.

[MELBA T.]

His dads is one sweet ride:D

[Whiteblownlt1]

ya not to bad for a 3rd gen:D

RS models, unless they're cop cars, don't have TPI. The cylinder heads are worse than TPI models and they have TBI. :D

[jmd]

PS: checking in; I swapped TPI into my Monte on the original engine.

What about mod for mod w/ an L98 350 not a 305?:cool:

[Stew]

I plan on putting aa TPI into my 92 RS.:D

[Mike98WS6]

I once owned a 87 GTA with the L98. It ran a 14.10 @ 96 mph. Not to shabby back in '93 with just a few bolt ons.

Run low 13's with bolt-on's

Oh wait, you can't

[jmd]

Nor have I ever tried. :)

[SlowLX]

But at least you don't have Quad shocks eh? Guess you win

[jmd]

So I couldn't possible run low 13's with a 5 litre SBC? :think: Not even if I tried? :cry:

You can do anything you put your mind to :shrug:

[TheCrazyTrain]

CHP got one down to 13.96@98.26mph
with just a

Holley Stealth Ram
Hypertech Chip

Add:
Headers
3 inch exhaust(possible cutout)
dragradials

You've got a mid to low 13 second car right there.




:p

The 5 litre was the best engine from ford at the time and the L98 was the best engine from chevy at the time. Its not my fault your manufacturer* doesnt believe in bigger displacement motors.:D

[BLURR]

Tuned port is the shit.

I have 1991 Trans Am with a 350 TPI and my dad has a 1991 Z28 with a 350 TPI. :D

A chip and a CAI made a 305 faster than a 350? I know GMHTP did a project car with a TPI 305 (Blue Thunder was the name I believe) and it took a lot more mods to get in the high 13's than a chip and ram air

:shrug: Are we talking a 700-R4 / 2.73 rear gear 350 and a T5 / 3.42 rear gear 305? There were a few combos over the years; I can't keep track. Fords were pretty straightforward. 2.73's or 3.08 with T5 or 3.27 with AOD. Hell, I think that covers most of the 87-95 V8 stangs, no?

well, of course the 350 is the 700-R4

Never heard of a stock TPI car (no matter what gearing) going 13's stock. I've heard of them doing it with a few minor SLP upgrades from back in the days, which I guess some would consider stock because I believe you could get them like that from the dealer, but I dunno. :help:

Not the 305 man the 350. The 350 ran low 13's with just bolt ons. BTW a stealth ram isnt ram air its an intake. Im comparing fords best engine at the time with chevys best engine at the time. I know jack squat about the 305 except there's guys over at third gen.org pushing them deep into the 11's with out much hassle.

TPI's run somewhere in the 14's in stock form. No stock TPI car could touch 13's w/out boltons.

HYPERCRAP CHIPS SUCK, DO NOT BOTHER WITH THOES POS!

Make your own:D :cool: Anything from a major company is crap. Its been proven, I can make you a better chip, and I have very limited experiance with PROM tuning and ECM scanning.

I know several 305's running 13's, 12's, and 11's.
And Im gunna have to go ahead and disagree with you on that.
305 G92 5spd and 350 cars with sticky tires and some weight loss can trip the lights at high 13 sec. Third gen gets no respect. and comparing an RS to a 5.0 mustang... should just compare a ferrari to a civic. I have seen 13 sec TBI cars, but not nearly as meny 13 sec 5.0's.
The fox body mustang's 2 biggest claims is light weight, and cheap parts. Third gen has the cheap parts as the SBC market is probably the cheapest parts ever for any motor.
Not to mention, the great clean looks of a third gen compared to the "escort" body style of the fox body.

What fantasy land do you live in? You see more TBI 305 3rd gens in the 13's than SEFI Mustangs? Or were you referring to 350's? Either way, it's the COMPLETE opposite in my area, but I'm not foolish enough to base what every car runs on how people in my area do with them. The 3rd gen get's no respect because of delusional owners like yourself, once again your main argument is that "The 3rd gen looks so much cooler!"

Also, for the EFI market, the 5.0 still comes out cheaper and easier IMO. Bolting on a completely new top end to a MAF equipped 302 is not a problem, while the same can't be said for the later model MAP TPI cars. If we are talking about carbureted well then I completely agree, the SBC has more options. Why don't you post up times for your Ferrari? Are you afraid my little stock motored Civic is stomping your guts out at the track? You constantly talk up the 305 yet never post any numbers on your car, and I've heard you mention you've been at the strip, did you forget to run it?. I hate to break it to you, but 305 vs. 302, guess who wins. Maybe 1 in a million 305's will be in the 13's with light mods, sticky tires and major weight reduction, but all the ignorance in the world won't save you from the facts.

TheCrazyTrain: Sorry buddy, I completely misread that, I saw Stealth Ram and for some reason saw Ram Air :confused:

Sorry about the confusion. I've heard of SLP cars running high 13's with just runners and some exhaust mods, like I said, not sure how true it is.

You misread me... I have seen some 13 sec TBI cars(305 TBI), but not as many as 5.0 mustang. EFI market is almost about the same. Outside of the price jacking you get by keeping with LTR set ups, a HSR intake with fuel rails and regulator all for about 500 bucks. A converted LT1 intake is 400 bucks and you get the same power as a TPIS miniram. Now, I know I have seen 5.0 intakes for that price and that doesnt come with new fuel rails or regulator. SBC parts over all are cheap. Heads, headers, cams, etc... are all cheaper then ford stuff, and there are more of them. Just open up any jegs or summit and there are pages of SBC heads, but only a few ford heads. And I was comparing the Ferrari to teh 5.0 stang and the civic is the RS.
My 305 TPI auto with peanut cam near stock ran 15.3@93mph. Crappy et, but not bad MPH. 60 is 2.2-2.3 with street tires. IMO for a 140k mile 305 with a wussy cam and auto, thats not a bad time. 305 vs 302 yes ok 302 wins I never said it didnt. Have I seen 305's beat 302's? Yes. Is it every time? No. Have I beaten a 5.0 on the street? Yes. Will you stop putting words in my mount? doesnt look like it. What ignorance? How is what I have seen with my 2 eyes be ignorance? Why dont you just fuggin losen up and realize that the 5.0 is not unstopable. You know, sometimes I wounder if all of the LS1 drivers were all once 5.0 owners. Same fuggin attitude from both camps.

im expecting 12.6 with my set up ;)

Expecting it and getting it are 2 different things Jimmy. :p

[#1WideTrak]

'88 GTA with 5.7 A4-3.27, 100K miles. Home-made cold-air kit, Dynomax, gutted cat, AFPR, initial timing bumped to 10 deg, ground down humps in the plenum, and relocated MAT sensor to airbox = 14.3s at 95 with 2.0 60' times on SZ50s. Prior to those mods it ran 14.8s at 91-92 with 2.0 60's with BFG drag radials. I hope to crack 13s with SLP headers I have yet to install. It's one torquey mutha...

[Hogie Sammich]

I had an 85 Iroc TPI 355, cam, long tubes, 100 shot... I like it, but sold it like an idiot :(

that is true blurr, but if you seen how much tire smoke i can put out, just imagine what will happen when i get all tha tpower to the ground ;)

that was my '87 IROC 305 TPI auto.

it had SLP headers, SLP "2OTL" cat back with a cutout, ported al. L98 heads, comp cam, and coverted it over to a 5spd.

[pmpn]

L98's suck. 5. slows suck even worse. I definately miss my '89 GTA but you really can't do much with TPI other than put an LT1 intake on it and SC it. If a 5.0 isn't SC, I'd even race it with my roomate's Focus. It's a good thing these engineers have improved HP over the years, well... at least GM.

yeah... thoes 350's suck. You like dont even see them in anything. :umm:

and you can do a lot with a L98 TPI engine OTHER then swapping an LT1 intake on it and supercharging it. I be you put a chip in your car.

350's are fine, however, Tuned Port is inefficient and severely limited including aftermarket; you failed to mention examples other than doing "a lot." No I never bothered with any chips.

And if you've never tuned one, well :rotfl:

And an LT1 intake is a port mis-match leaker. Gotta go Mini-Ram or Stealth Ram or other options...

TPI is only "severely limited" by the stock intake. The efficiency is quite contemporary, given the engineering for it was from the early 80's.

I've owned an 89 GTA 5.7, 87 IROC 5.0, 91 5.0 LX and now a 99 Z28. Trust me, I'm no expert but I've done my research and I've worn the shoes. I'm not saying they aren't nice cars because they are but the motor leaves much to be desired IMO. Certainly I'm entitled to that.

The SBC doesn't leave much to be desired, but...

The intake leaves much to be desired. The EFI aspect of things is reasonably contemporary.

Except for the batch fire aspect of it, the 86-89 and 90-92 TPI ECM's are every bit as good as the EEC-IV stuff Ford used on your 5.0. I welcome your retort to that. :)

[Redballboy]

wow u guys really make the TPI engines look a lot worse then they are. they are just really restricted they go really fast for what they cost and with minor bolt ons go 13's and ive actually seen a couple stock go high 13's with just some z rated tires and maybe one mod nothing big though. there are a lot of things u can do to just the TPI setup itself, airfoil, large tube runners, replace the intake and port and polish it etc

Very very doubtful they will work. Turbo headers are an extremly big pain on 3rd gens. I'll assume they are log manifold style? Even then 300 would be a steal.

[norcalz28]

TPI isn't that bad. Its just restrictive with the LTR design. It would have been a perfect truck injection setup, delivering all that low end torque.
But the truth is w/o the lessons learned from the TPI, The LT1 would not be what it is. I mean what makes the LT1 so different? Its basically a reverse cooled, short runner L98 with a radical ignition system. Still a SBC, GM just figured out a way to give it more top end performance by sacrificing low end torque. Its give and take. You can argue both ways which is better. But they are two different animals, and both products of their time. With the way things were looking in the 80's, its a wonder we got EFI to become a standard, and perform the way it does, at all.

Alot of people fail to realize that the TPI came about in a time when increasing strictness by the EPA and other pollution controls were threatening to make performance all but extinct. GM turned around and created a system that, FOR ITS TIME, was extremely efficient in every aspect of its performance. Of course these cars are gonna seem like dogs by todays standards. They did however set the stage for things to come.

TPI is a great system, its just too bad the aftermarket is not so generous.

Will

[rushhour]

I agree with norcalz28 - great engine for its time and compared to todays cars - relatively easy to work on, especially on the electronics side.

I bought my 91 Z28 new. Added headers, Accel manifold & large tube runners, TPIS chip, airfoil, trans kit etc.

Cried when I gave it to my brother in Dec with only 68K miles on it - a new GTO took it's place. The deal was that he couild have it - but if he couldn't sell it - had to give it back. I am going down to his house this week end to work on it - replacing all of the window seals and tuning up the engine.

As good as the GTO is - believe it or not I miss driving the Z every once and a while. That car was just a ball of fun.

[Neil350]

You can make a L98 car run, under those crappy heads, restrictive stock set up, its still a Small block Chevy. 2 bolt, but still a SBC. Set it up right and it could run like hell, I really want a 91 C4 Vette, SBC and a six speed. So much potential for that motor, this TA is going to be my only Lt1 car.

[Goat LuvR]

This was my attempt at building an TPI L98, seemed the more parts I threw at it the slower it went... :rolleyes:

I have some really good numbers at home from TPIS with their TPI Corvette. I think they got it to run 12.0 with large tube runners and a big mouth base and a mild cam with ported stock heads and headers.

The L98 is a very good engine. I have always loved them.

[Rottluver]

I am DYING to get another 3rd Gen F-body and I want a '91-'92 Z28. I plan on making it (if it isn't) a 350 and converting it to a 6-spd, using this motor:

360 hp TPI 350 V8 (http://www.sdpc2000.com/cart.asp?action=prod_detail&catid=1577&pid=9009)

Not to shabby for a start. :D

[norcalz28]

3300 though for basically a smallblock with the lt4 hotcam? I mean this is exactly the route I was going to take, but figure you could prolly do it for less. The heads/intake could prolly be had for around 1k. Figure another 1k for a good longblock. and still adding in the price of the cam, better rockers, all this stuff, new runners, you could still have some money left over to maybe get some nice valve covers or whatever. It doesn't say anywhere about it having any radical internals. It just seems a little steep for me. Not to mention the shipping fees. But this is exactly the route I wanted to go with mine. The car is never gonna be as fast as whats being put out today, but with all that low end torque, it makes for a nice street car. IMO its just nice to cruise
around and be able to launch like crazy. Can't wait to get mine back on the road

Will

[Rottluver]

I am sure you could build up a very similar motor for the same or less....I was just using it as an example of what is out there for the TPI crowds.............and that you can make good #'s with TPI. Doesn't have to be with that particular block......... :cool:

A fast injected 3rd gen in my area is like a fuckin unicorn. The fastest I know of is my friends 355 with AFR's and a decent sized cam. Can't remember what intake to be honest. He's switching over to a TH400 soon but with the 700, a 9" with 4.10's and some custom tuning he did on his laptop (using an Ed Wright chip as a base) he ran 11.51. Very impressive car
