COMPLETELY stock engine, what is max boost, power, and times??

[fbodlovr]

I was wondering what the max safest boost would be on a 100 stock motor. The only thing done is walbro fuel pump, hotwired, afpr, scanmaster, fuel pressure gage, boost/vacuum gage. Have adjustable wastegate, just havent put it on.

I have a 2000 camaro z28, and I am curious to know if the gn the way it is, if I turn the boost up, if it would beat my camaro.

i would say 18psi,thats pretty much would i would run unless your going with race gas or alky

I don't see a exhaust systemi would say if your gn is a hot air car your running about high14' to low 15's with 18 psi

lol, I thought my sig said it all. It has been converted to the intercooled setup. And no, I dont have an exhaust system, just factory. Although I dont have a cat right now.

But, do you guys think it would pull on my camaro if I DID turn it up to 18psi?

so what your saying is you have a 86or87 engine in your gn or is it a 84 engine with a intercooler add on

I took out the 84 engine, and put in a complete 87 engine, intercooler and all. :biggrin:

well thats all you have to say i dont see you having a problem with the camero,the camero run low 14's to mid 14's.i would recommend at least up grade your exhaust system and some kind of scanner to keep an eye on your motor.

to give you an idea my gn 6 plus years ago with just a k&N filter tt chip and my exhaust system ran mid 13's with 16psi all day long

Well, I do have a scanmaster. And my camaro runs 13.5's stock. Do you think this would be much of a problem to acheive?

put the adjustable wg on and slowly turn up boost watching for knock

on 93 octane, it will max out anywhere fom 16-20#, more likely on the low end of those numbers.

If you put 100 octane in,you will getter better boost numbers and should be able to get better than 13.5's

Say I did go up to about 18 psi, would it just be as fast as my camaro is at that point? And if I added alky and a chip, would I really by able to crank up the boost, and seriously stomp my camaro?

If you added alky, a tt chip, and a cut-out (assuming reasonable 60') you wont want to drive the camaro anymore

Im guessing at 18 it will be real close to the camaro, maybe a bit faster.
If you had a better flowing exhaust id give the gn the edge

If you added alky, a tt chip, and a cut-out (assuming reasonable 60') you wont want to drive the camaro anymore

My son has a 2002 Z28. It's a 6 speed car, 89K, and stock except for an air lid and a K&N filter. He goes 81MPH in the 1/8th.

9 years ago when I bought my completely stock 21K TTA, I busted out the cat, added a K&N filter, an adjustable fuel pressure regulator, an adjustable wastegate actuator, and a Red Armstrong 100 octane chip. Then I put in the 100 octane gas, tuned it to 21psi of boost and went 86-87MPH in the 1/8th all day long in 85° weather on ZR rated radials.

Now, with all of the basic bolt ons complete and the TTA going 89MPH last year, he has absolutely no desire to get anywhere near my car with his Z28. :biggrin: One other thing, an 8MPH difference in the 1/8th is a pretty bad beating, but it looks MUCH worse on the street from a 20MPH kick with no 1/8th mile marker to stop the race.

Years ago w/ a Ta49 on basicly same set up as you, plus 100 octane, 23 psi my stocker went 7.69's in the 1/8 at 90 mph

Thats a good number! What was the 60ft?

I just took my car out today, and when I got on the gas I got a code 13. I have seen that this can be caused by an o2 sensor going nutty. It can sometimes have an idle that goes up and down a little. You think its the o2 sensor?

I can tell you this, in 1987 when we had REAL pump gas, not the re-formulated crap being sold now, a bone stock 1987 would sometimes have audible knock/ping. The stock setting is 15-16 psi.

Since I have replaced hundreds of head gaskets on LOTS of GN's since then, I can assure you will be doing the same to your car if you turn it up on pump gas.

I keep telling the local guys do not run over 14 psi in our normal weather without good gas, like at least 5 gallons of 100 octane in the tank with the pump gas. Guess they learn the hard and expensive way that I have more experience than they do.

I learned by making the mistakes over the years, so they don't have to make the same ones

The guys with alchy kits keep me especially busy with head gaskets and more by pushing beyond the limit!:biggrin:

I don't doubt that one bit because alky will tempt you easily, but if I screw it up, I'm fixing it!

My T Type when it was "stock" it did have a RA93 street chip, K&N cone filter, adj. fuel regulator and XP fuel pump. With 100 octane, 20psi of boost, drag radials with a 5 psi launch my car ran 7.80's 1/8 mile.

It had the stock exhaust with no cat.

HTH

I have found that the best mistakes to learn from our definately not ur own so I think I will take u up on that and put 100 in mine when it gets finished. There is a gas station local that has an actual pump so there is no excuse I guess.
