Thread: Guess how much power I will make with GPF math

you also displace more.....

Lol I'd commit suicide if I only made 270-280whp with all those mods. On a 3.4 gen 3 with rockers and headers I made 248whp STD.

This makes me feel mildly better

If I had to honestly guess, you're close to 300whp STD. My first thought was 310whp due to the other mods, but I'll say 300whp to be conservative.

Well, hurry up and get this sh1t going.

I want real numbers, now.

Well I should have my shortblock back may 6th-10th and I need to leave for ocean city may 16th

If I get it may 10th it will be a 48hr redbull fueled reassembly. I then plan to drive it to Washington DC from Delaware and back which is about 400 miles then to NJ to the tuner 500ish miles there
Have them change the oil there then put the car on the dyno for a tune and hope it doesn't blow up. Once all this is done I will report back with numbers..

Powerhaus Performance "the heartbreaker".. lol The tuner here left Race Proven Motorsports (RPM) to open his own place.

seems like a lot of driving with out a tune. NJ first would be my choice.

its tuned now for less timing, and the new injectors so I can drive it safely. I don't want to beat on it or the new trans before I am done breaking it in.

trannys are like a rebuilt motor, its go or blow, theres no more break in times for the cam either, as they all got roller lifters now.

only thing you should do is the oil change 300 to 500 miles later.

its been said beating on the new engine right out of the box helps seat the rings too.

Interesting... Well this is good information and takes a **** ton of stress off of me.

How much power with GPF math?


7000hp broooooo


z06 by a bus, vids to come

I've seen and heard of people making 270-280ish whp with rockers. Cant see why you wouldn't touch 300whp with a cam.

yeah, you can baby it, but in the end it wont matter, if its gonna blow up, it will blow up being babied as well. tune = hammer time tho.


back in the day, a rebuilt engine got 30 minutes at 3,000 rpm, to break in the cam, then it was ready to be flogged, now a days thats not needed at all. tune it, and beat it.

I was simply making a point as to what numbers he could see... BTW don't forget the fact your rolling 3.29s and Anmar only has 2.93s. I am interested to see the numbers after on converter and fuel pump.

Scuse me? If your talking about me... i'll just leave this here.

I wish I could do e85. I know of one pump in the entire state of Delaware.

You should easily make at least 300whp. If not it will be a bit higher.

You would post the video of me litterally 5 mins after filling up with e85. I litterally only scaled the injectors. No timing or anything. Not fair.
