I just got done making some changes to my E85 GT3076R Evo and here's the results!

Mmmmm, I love me some Evo's

 

Sick..dyno pulled sounded nastyyyyyyyyy. Now get some videos of that bitch rippinnnnnn

 

That is pretty nasty but I know there is plenty evo's out there with better turbos making 550 to the wheels on 93.

 

Lol, better? define better.

This is a road race car setup specifically for Redline Time Attack Street AWD class.

Its not going to live its life 10 seconds at a time so the tune has some built in conservativeness.

I did 15 pulls on the dyno that day starting at 461awhp and ended at 530awhp. and saw virtually NO KNOCK the entire time.

Basically what I'm saying is, I could have gone higher. I went to the dyno that day wanting 530awhp and I got 530awhp.

 

Haters gonna hate....Nice car!

 

need to find the restriction. power shouldn't drop like that up top. unless you have stock cams.

 

not stock cams

thats above my rev limit. I upped it for the dyno so I had time to let off. What you are seeing is me letting off. You can basically clip that off the chart.

 

sick sick car man, i look forward to getting one as a toy down the road

 

what im seeing is from 6300 on up, power is dropping. it could be boost dropping as well. depends on how the duty cycle is setup, if running the stock ecm with a mac/aem valve perhaps.

im just going out on a limb here

 

Sorry if I was "hating". Your car is sick and I would take your car over mine in a heart beat. Congrats on the numbers and good luck at the track.

 

Its port efficiency. My logs indicated that up around ~6500rpm I am flowing less air than at 6000rpm.

I decided against a port job because it will slow down inlet/exhaust gas velocity across the board which will lower low end power/torque, effectively move my power band right. I dont want to do that because of the stresses a higher rev limit puts on an engine. For instance a rev limit increase of 1000rpm has an order of magnitude higher stress rise on connecting rods than an additional 20psi of boost.

It also has tradeoffs in fuel mixing because of the lower reynolds number and hurts fuel economy and makes it harder to tune (O2 sensosr will say its rich, but its not the air fuel mixture thats the problem, its actually combustion efficiency, left over fuel AND oxygen.)

I basically just dont want to operate the car while racing in the 7000+rpm range.

 

if you're still on the stock short block, id highly suggest rod bolts. for obvious reasons. personally have seen too many of them come flying apart at 500+whp.

being that you don't drag the car, the powerband will work peachy for it

just different than what i am used to seeing in the evo world. reminds me of a subby curve

 

Give a Subie owner a Evo and end up with a Subie curve

Its a fully built block. This isn't my 1st 4G63 rodeo.

 

valid point, lol!

 

Impressive man! Looks like a pretty nice powerband for that setup
