I want to know how fast you can go with the tpi design system,when says tpi design i mean use aftermarket intake manifold siammesed or large tube runners and ported plenum but still using the factory 350 motor.It can be accomplished with aftermarket heads and naturally aspired engine. And i like to have details in what combo you use to achieve the results.I like to see how hard is to put a TPI fbody to run in the 11s on pump gas in the 1/4 mile and still be street legal.
Thanks

 

your spelling is terrible. can you speak english?

your question has been answered a million times.... DO A SEARCH

 

Street legal where? It makes a difference if you have smog check or not.

All you need is money and by the time the motor is "in the 11's" you will need to upgrade the rest of the car.

 

He's from PeutoRico so I'd say no, he proabably cant speak english (well).

If you took the time to read your self you would have realised that this guy isnt an american and that mabe just mabe it's not so simple for him to read these posts written by people who commonly speak poorer english than he dose.

I was born and raised here and it's hard to decode half of the crap on this forum


As for what it takes to get a TPI 350 into the 11's, I'm on the same journey my self and with all the mis-information I have to sift through it looks like getting solid info is the hardest part.

I have seen several TPI 305's and 350's in the low 12's and 11's and it seems they require all the same things any other car dose but with special consideration to the cam profile, ECU tuning and a healthy investment in atleast a set of runners.

You can move the power peak upto about where it would be with a mild street carb intake but with a bit less peak power and a lot more mid range torque. You need to keep that in mind when selecting a rear gear set and a converter if aplicable.

If running a T5 you will be pushing it pretty hard at that point, so either plan to swap to something better or start collecting spares lol.

 

Thanks "ls six" for a great explanation on what happen in this forum.
To make the long story short, i going to buy a 91 z28 that back in the 1996 was mine.In that time the car ran 12.4s @ 110 miles 1.7s sixty foot .It has a tremek TKO 5 spd,9" rear end with 4.11 . In the motor it had at that time 224/230dur. 510/525 w/1.6 rockers and a set of trick flow heads g2. Now the owner of the car took out the cylinder heads and put a set iron heads.The rest of the car remain the same.I going to put back some heads but i want to push the car in the 11s if i can. Now was so many years out of the tpi field and i want to update my knolage about them .

 

Hey pal, I looked at his info and I have no idea where Camuy PR is. And the fact is, his question has been answered a zillion times here. I've been a member of this board since 1998 (under a differen name) or whenever it started, I know he'll find what he is looking for, this topic has been discussed on this forum for 10 years now. I'm sorry that he doesn't speak english well, but this is an english speaking web forum, so either learn the language or don't come here. Complaining about it was not one of the options.

By the way, your spelling sucks too.

 

No problem man, it sounds like your awfully close to 11's allready assuming the last owner didnt handicap it with those heads.

Do you happen to know what heads they are? As long as they arnt 70's large chamber light weight castings ( you'll have to look up the casting marks and numbers to be sure) or TBI tumble port heads they cant be any worse than stock TPI heads.

If they are Vortecs you'll be in the 11's easily enough with the right supporting mods.

I hear Musclecars are big in PR but I dont know what resources you have down there or what budget you have set.

Let me know what you have on the car now and we can easily work out a good combo



Racist much? Pathetic.

 

Hey dude, that was across the line. Race was never mentioned in any of my posts, and has nothing to do with the topic. Again this is an english speaking board. If you can't speak english, then don't waste everyone else's time because we can't understand you either. I feel strongly about racism, one more outburst like that accusing me of such and I'll report this thread to the mods.

 

I dont care, goodby .


If you decide to bring a mod in perhaps you would explain why you feel you can decide who is welcome on this board based on a persons region?

 

The person's region is irrelevant. The fact that they can't speak english is the issue. Why do you insist on turning this into a discrimination case?

 

Your making yourself look more like a a$$ in every post, if your not going to helping someone out don't bother posting please. We don't need a spelling moderator gesh!



fastsspr can you give us little more info on your engine like intake, heads, what exhaust system you have on there?

 

I'm sorry you feel that way. I'm just trying to tell someone to use the search function on a topic thats been beaten to death, then I get accused of being racist. Now I know why I don't come to this site much anymore....

 

You make it sound like everyone around here is running 11's which is total bs, I've been on here since late 90's to and really there is only a handfull of people on here that have done it with a 5.7L

 

No, people like you are the reason people like me DONT come on here very often.

DO A SEARCH DO A SEARCH DO A SEARCH

thats all some people ever post!!!!

Well....

1) the search engine aint that good!!! often bringing up complete rubbish
making it quite hard to find what you want.

2) Whats wrong with asking a question... ANY question, even if it
has been asked before? it dosent hurt anyone does it?
and you might even get a better answer than that which
has been posted before.

3) if nobody ever asked a question thats been
asked before.. then guess what.... there would be next to NOTHING
on this forum, coz there is very little that is totally new or never been done! Be a pretty dull forum

4) "Do a search" is just plan Rude!
If you cant be bothered to answer a question... then simple....

DONT ANSWER THE THREAD!!!



As for moaning about the mans english!!!!!!
Cant believe i saw that
Sorta thing mods should be deleting,



As for your car mate 11's
I have seen it, but it was quite a wild set up,
one hell of a cam mind, but your was not too far off
so it should be possible.
Tho if it ran 12.4 before, then even when you fit
some decent heads back on you may need to go with
a larger cam.
Or... just add some spray to push you over the edge
at the track.

 

OK.....The OP has a reasonable excuse.

So whats YOUR excuse for YOUR bad spelling? Your post made my eyes bleed after the first 2 paragraphs!

 

For **** sake, its another one,
what is your malfunction??
This is a forum, not a school spelling test?
So stop acting like ******* school kids,
Pathetic!

 

Just because its "just a forum" it doesn't mean proper spelling to be UNDERSTOOD shouldn't used.

If a person can't comprehend basic spelling, are we supposed to take anything the person says seriously? NO. I ignore idiots.

 

If you seriously had trouble understanding what he typed,
then... man... you have issues.
The odd letter missing and the odd mistake is hardly difficult to read for anyone
with half a brain
It hardly makes him an idiot does it.
My typing aint brilliant, so i sometimes miss letters myself,
NOT because i cant spell, but because i cant type great.
AND... does it matter... to anyone without a problem!!! no, of course not.

And if his such an idiot.... and you ignore idiots...... then why?

why?

did you feel the need to reply with such arrogant dribble!

 

For one it's not means suggestion that the OP search it was his suggestion that the OP's lack of fluency in english makes him less than worthy of his advice or this forums resources.

Two, Yes HOFF this forums search function is very weak It either returns nothing or dozens of barely relevant posts.

As for my grammar, everybody who has a problem with it can stuff it .

When it comes to spelling I really dont care as long as the person doing the typing dosnt fill the screen up Wit, sTuf lIek dis Not grammar from americas poor educational system but idiotic punctuation and spelling that needs a codex to decipher.

And in those cases I just walk away, I dont throw insults around and start ****.

 

Hey i don't answer your first post because i do not care about people who have nothing positive to throw in the table.If you rode the title of the post and not like it well ,no read it ! Pass over it... You are not the owner of the website so don't bother other members with stupid comments.If you do not know where Camuy PR is.Go to google and do search and find it.

Honestly i have no idea on what heads they put on.Someone told me they use a set of ported 305 heads. That mean they are bottle neck for the motor. I so in ebay a procomp aluminum heads 210 runners with 64 cc and 2.05 1.60 valves for $584 i think can be a good deal and can weak up the motor again to be i a solid 12s. Them i have to start again the trail and error to see if i can hit 11s with the car. Looking in my garage and find out i have the DFI i bouth for it back in 98,is a gen 6 and some 55 lbs injector.The first thing i going to do is install the dfi and see the results.Them start from there to deside wich heads to buy. I will keep you update in the progress but it going to take some time.Because have other priorities now than the car.

 

Oh yeah lol, 305's will definitely kill the top end. And I believe the compression would be raised a couple points as well. I wouldnt be suprised if it pinged on lower grade gas.

That reminds me, what grade of fuel are you planning to use? I'm not sure whats available in PR from the pump.


As for the ProComps, that looks like a good price if thats for both and they seem to have a decent reputation for the price. Everyone who runs them seems to think that porting is mandatory with these heads in order to see results worth the drop in initial quality.

These are Chinese castings and early versions were very low quality.

I would proabably try the 190-195 port version if I was planing on keeping the TPI setup. And if you can make it happen go for the angled plug version. You will most likely need headers designed to clear angled plugs for that.

Keep in mind that what you get isnt going to be as nice as say Dart heads, I look at them as being in the same legue as ported (new) Vortecs, ported Etecs and the very best heavily modified stock heads. Al require a bit of work by you to get the best bang for the buck.

If aluminum isnt the most important thing to you I would pick up a set of used Vortecs and go to work on them. By the time you invest all that time in porting and the tools needed to modify the valve guide boss/spring pocket and either buying a Vortec base or making the mods to run your stock one you'll be close to the out of the box cost of these heads but I do think you'll make a bit more power.

 

Yes ,you are right. If i buy them i going to send them for a porting job to a friend who really know how take out the potential of cylinder heads.But in the long run probably i going to spend almost close to a set of AFR.

 

Dart Iorn Eagle platinums are a good head .They can be bought for a reasonable price.They have very good flow numbers.

 

I looked them up and the lit, and pictures show a heart shaped chamber and claim good "combustion control".

Do you have any experience with these heads in high comp low octane situations?

Flow is important but since the TPI will ultimately determine the breathing capacity of this motor a good chamber is what I would look for over anything else.

 

If you ignore idiots, why are you replying to this post?

 

You may have seen my motor build. I have a modified TPI system with the factory plenum(modified), SLP runners(modified) and a First intake manifold(cleaned up the ports). Currently I'm at 12.12 and 111.27 in the quarter mile with an A4. With a few tweaks I expect to break into the 11's.

With my new Motor build that will include AFR 195 Competition heads, a slightly bigger camshaft, a 6.0L motor, a raise in compression to 11.15:1 and exhaust termination boxes I expect to be able to get to an 11.5 in the quarter mile. This is with a California smog legal car. I will turn on my signature.

 

To Original Poster:

Honestamente la tecnologia the injeccion electronica a cambiado mucho desde 1996, specialmente de T.P.I. Pudes llegar a los 11 pero no creo que is posible con el systema original. Como mucha gente a dicho, por lo menos tienes que aumentar el tamano de las "heads" y el TPI. Lo mas recomendable is es obtener el systema de TPI de Accel o Edelbrock o otra compania aftermarket. Lo mas mejor seria el systema de F.I.R.S.T. Cuesta mucho mas pero con ese systema puedes alcanzar los 11 y hasta los 10 sin modificaciones el intake. Lo demas ya seria cuestion del motor...

 

If you are running a camaro then you can go with a Holley Stealth Ram. Much better on top end than a TPI however a little weaker down low on Torque. I run the TPI on my GTA with Saimezed Runners and a 58 mm throtle body. I have a 355 that makes roughly 450 hp. You can easily do that with a TPI.

 

i just read your remark and puerto rico is America. everyone born there is an American.
its not a state so no representation in the house or senate, or even vote from president. that is limited to states. same reason why dc does not have them, its a district not a state.
and American simoa too.
end of lecture.

 

Honestly the electronic injection technology has changed much from 1996, special T.P.I. equipment is needed to arrive at the 11's but I do not believe that is possible with the original system . Like everybody is saying, at least you must increase the size of " heads" and the TPI intake. But the recommendations are to obtain an Accel, Edelbrock, or another company aftermarket TPI system . But a F.I.R.S.T. is a better system much easier with that system for you to reach the 11's and into the 10's without intake modifications. The other serious question is the motor…

This is a modified Babel translation for the uneducated.

 

not bad at all for Babel fish translation, most of the time it doesn't make sense...

 

Sorry for the misunderstanding.....I'll ignore YOU from now on.

Back to your regularly scheduled thread......

 

So again you say one thing and do another. If you think I'm an idiot why did you reply to my post?

 

Patriot aluminum heads are very reasonably priced about the same as the iron eagles. I like The TPI siamezed runner from SLP myself. Another good design is the Holley stealth ram, you can get the manifold alone for 500 dollars or so and transfer your injectors and so on over.
