How far can the engine be pushed with stock internals on pump gas ?

[Ricardo]

I'm looking for people who have put good numbers on the dyno or at the track with stock internals. No headwork, all stock engine and head.
Anyone ? Don't hesitate to post even if your numbers are not impressive... thanks!

I heard 400hp @ wheels is the max with all stock internal

I've heard low four hundreds. Planning on making at least 400whp this weekend on race gas.

How much power you can reliably make on pump gas is going to have more to do with your EMS then the actual strength of your internals. If you don’t have any control over timing you either will have a hell of a time hitting 400hp on pump gas or when you do get there you will have a lot of headgasket issues. The strength of your internals should be the least of your concern.

Who have you heard that from? There are only a dozen or so people out there making that much power on pump gas.

A few members from NABR. So it must be true.

Hey Mario are you going to go to dyno comp? Im going to california this weekend so if you are that sucks cause Id like to be there. Anyhow Im going in two weeks. Im in the middle of installing my GT-12/vpc...etc right now.

Not to jack your thread or anything. The highest Ive heard of on 93 pump was 435whp...

You must have heard wrong. A 7bolt motor is only good till about 400hp or so but no one there would ever say the limit of a 6 bolt motor was in the low 400s. Trust me

A friend went 12.2@104 on pump this weekend hitting the brakes hard because he doens't have a cage. He's consistently trapping around 115ish. He hasn't dyno'd, but I would guess he is nearing the 400hp barrier. He does, however, have a built 6 bolt motor so this won't help you much. This was @21psi and 19 degrees of timing or so.

I made 355.5 whp on 18 psi 92 oct pump gas about a month ago. I wanted to go back and run 22-23 psi and try make 400 whp on pump but my turbo failed soi i haven't been back.

I just got my setup in the car and Im still sorting out a few problems but I plan on dynoing my car within the next few weeks. I will post up some numbers when I get done. I will be running 93 octane on a stock block and head. Im not even sure what the hell is going to happen when the car hits the rollers. I do know this setup has the ability to make more than the stock engine can handle but that doesnt mean I will make that much power.

Keep us informed !

Just about every reply on here has not answered your question. They have all been about race gas, 6 Bolt engines, built engines, etc etc.

As for YOUR question: People have put down around 400hp on a bone stock 7 Bolt 2G engine. This is with good tuning, lots of fuel, and a nice big turbo (usually a FP Green).

Hope that answers your question.

What kind of boost do these guys usually run on pump gas???

25 psi?? More??

I run 25 on pump but just because my wastegate opens at 25 psi doesn't really mean much, because i drive like a ####y most of the time.

People get somewhat desensitized to how much HP 350+ to the wheels actually is on an AWD 3100lb car. I would be very very happy with 350'ish HP to the wheels in my daily driven street car.

I don't really car much about records or comparing numbers. I just like a nimble fun to drive dsm
