430T/A

I think I Have a recipe for 15 second 2.8/ 5 speed

first off 5.13 gears, and with the newer T-5s with the 4.03 first, thats like a 21:1 advantge.

Slicks and major suspension work would be in order to get it to hook.

Port and polish plenum, manifold and heads.

Bump timing to like 15 degrees, and run 94

cold air and more cold air.

remove all accesories except alternator.

Gut the car completly. were talking drivers seat, wheel and shifter thats it

bump up the TPS sensor so it idles 1500 in fact, pull it off, and tie it in place so its at a little less then full throttle, all the time.

like a hundred shot of the juice,

this sounds dumb, but using a leaf blower as a turbo, rig it so it only kicks in under full throttle. a Bit of adjusting needs to be in order here, so stick with it, it works just as well too.

pull off the whole exhaust system, and either buy headers, or jus pull the manifolds off all together. the loud noise will distract the tech guys from the leaf blower anyway.

un plug knock sensor, it will only kill the 15 degree advance.

snake some big injectors from a tpi, you'll need them to support the boost and the juice

remove all glass, and cut out all unessary metal.

I think this should be good for at least 16 seconds, and if the turbo-leaf blower works I think 15.
it will be practically undriveable, so don't even bother to put plates on, besides its only extra weight.

at any rate, what does a stock 2.8 run anyway? thanks

i hope ur kidding...

why don't you just save your money and just drive it off a cliff. That'll get you 15 secs..................Vertically.

oh I definatly am, but the 5.13s would be cool, as long as no money was spent on them.

Go ahead and try, you will prove yourself wrong.

Now I know you're full of $hit. Get a life.

Doward

Tie it so it's a little less than full throttle, all the time? You realize you won't be able to STOP THE CAR?

Not to mention on startup, yeah, you just blew your engine spinning 10k+ rpm

Well tuned 2.8 + 75-125hp shot of nos = low 14's, 13's with traction.

yes that sounds dumb verry dumb

430T/A

yeah I was definatly joking around. I have toyed with the idea of trying to get a 2.8 in the 15s or so using a real turbo, not the leaf blower. who knows

Adidas3k

i was bout to **** my self i was laughing so hard

Joe_L

That was good for a laugh.
Atleast your joking and never said, oh yeah I did this already, and when we ask for pics you come up with a lame excuse.

Err...my lug nut fell off and I put the car into a river; excuse.

2 things-

You guys missed the TPS thing. as you all must know, being the 2.8 gurus you are, the throttle position sensor is adjustable, to improve idle and gas mileage and overall driveabilty. IF you set it stupidly, like taking the senor itself off, and tie the tab or glueing it about to the floor, the car will idle high, but not tach up until it gets some air, meanwhile the injectors are squirting a big punch. its a stupid method, and I doubt it works. but it might be neccesary due to the the leaf blower.

by the way, I had a friend try the lea blower idea on his snowmoblie, and he said he seized the motor almost instantly. apparatnly he blew the gas back into the tank, filled the cylinder up with gas and air, and the piston couldn't compress this, and the motor was spinning ata bout fullrpm when he did this, and the piston melted to the walls. he is a dumbass, way to much boost for a snowblower. I wonder if you could een call it boost?

and I am glad to see some of you are enjoying the humor.

for the record, I am not bashing 2.8s in any way, and I respect what they are capable of. I am actually building a 3.1 stroker motor this week. if you have any info on how to convert your 2.8 to a 3.1 by all means just ask.

thanks, and sorry for pissing you guys off so much

Joe_L

Well you never pissed me off, found it pretty funny. As for the TPS I was wondering what was going on with your idea, cause if that was unpluged on my car it wouldnt even start.

if you want a 15 second 2.8 that is actually drivable look in my signature.

camaro89dude

5.13 gears...wouldn't the car gear out before it even made to the end of the 1/4?

Project: 85 2.8 bird

get a 6 speed, and maybe a gear vendors unit.

OR

put some JATO rockets on it & get a 7 sec 2.8

SlowCamaro88SC

as soon as you unhook sensors the computer will use default conservative factory programming in absense of a signal from the sensor.

why even go all that far on a 2.8 maro to hit 15's?? I can see if you don't have the money, hey I once was there. but you'll do better buying something already in the 15's. ( or something newer that actually has an aftermarket. every year that passed the aftermarket for the old school 60* v6 dwindles)

it's not really a bastard motor, it's the base motor from dating back to 1985.
17 years ago.

as far as you really can go as far as advancing the TPS is about .058mV

for newer t-5's if you are talking about after thirdgens none will work.

unplugging the knock sensor will only allow the car to a maximum of, IIRC 20* or so of advance, thus killing acceleration.

leaf blower will pull less vacuum than the car @ idle

did u guys ever get headers?? I know when I left like a year and a half ago, they were still workin' on it.

and oh yeah, the car will never pass tech inspection.
