Hi I was jus wondering how this set up will do. I have ran a constant 15.0 in the quarter mile in a 1986 5.0 tpi and was hoping with a new cam and intake manifold get to 14.3-14.5 would be a good goal to set with wat i have done. So far this is wat I have done switched from 2.77 to 3.27, accel 19lbs injectors, dui hei distributor, accel shrty plugs, msd wires, hooker 2055 headers, high flow cat, bbk afpr and fuel pump, 1.6 roller tipped rockers, doube roller timing chain, bbk underdrive pullies, ported and siamesed my plenum slp runners and edlebrock high flow base, cam specs including the 1.6 lift is 450/472 duration is 204/214 @.50. curious to see wat it will do almost done with it, tell me wat you think.

 

IMO if you get good 60 foot times low 14s should be a no brainer. On a really good day I would not be surprised to see a sub 14 with a sub 2sec 60 foot.

How well is the system taking to the mods?

 

its almost done havent fired it yet i had some tweaker come thro and steal my radiator and tranny cooler so kinda on a set back and i been wantin to see if i could put some type of iroc intake on it do some ducts right in front of the airdam has anyone tried that on a firebird set up?

 

i had a '91 Formula i did that to. It worked great all parts were from from Home Depot. I used black plastic gutter dran collectors for the scoops one on each side in front of the air dam. I ran flex hose from each scoop into a Y at the air intake on the passenger fender. From teh Y i ran flex hose into a conical filter so it had a ram air effect. I thought it worked perfectly on hot humid days.

 

sweet yea that was my way of goin about gettin as much air as possible without using a ram air hood im hoping that its goin to be pretty quick lil sleeper gettin people at the stop lights... anyone got anything idea about hp i was thinkin 260 idk if im off or not i got a good dyno/tune shop so not too worried about the tune any more suggestions would be helpful

 

I think you will get wiped out by a red camaro with a TBI engine
just my







oh yeah!

 

Did you really just talk smack using smileys?

 

If you look at they're location they live in the same town, so I figure they know each other already,lol

 

Well I guess thier is one smart TPI owner...haha..

Obviously yeah we are friends and I was trying to be stupid and funny.

 

lmao...

to OP ... do you have headers? or are you choking your engine with the OE manifolds...

 

he has hooker headers, not too much longer and his car will be fired up again and then racetrack time

 

I take it you don't hang out in the TBI boards much huh? lol TBI all day every day bro,lol check out my cardomain for everything else.

 

oh yeah duh i didnt even realize it. I take back my previous statement about TPI owners...hahahah

 

... ... went back and read the post... indeed he does...

 

lol i need to see your car at the track anthony sounded pretty good when you got on it the other night... cut outs are bad *** haha

 

i love that freakin cut out instant hearable 100 horses...lol...with my cowl hood i already had an instant 100 visible horses so my lil 305 is pumping out almost 400 horses..lol...as soon as i get my tranny problems resolved ill be inline at the drag strip

 

bump... anyone else have any ideas to wat else i should do or suggestions... wat about the exhaust pipe would i benefit from goin 21/2" to 3"??

 

2800 stall speed and drag radials out back. If you dont get mid 14's out of that setup with new intake and that cam with a tune to match, somethings wrong.

Your biggest ET gain will definatley be the 2800 stall on good tires. 1.7x 60's shouldnt be a problem with TPI

Is it an aftermarket/custom 2.5" catback or something right now? 3" wouldnt be a bad idea and give room for future mods like a new 350 or nitrous setup

 

I would go to 3" when you can. Let's get her going again and see what she does and then do the exhaust and see what you gain/lose
