Evo IX 2.4L Sheepey Top mount 6765 R2 AMS F1i E85 WG pressure vs 43psi

Me and Egor have been tweaking his car for some time now. With the help of our good friend/customer Andrey we have a lot of custom fabrication work done to this car.

Mods on this car are as follows:

2.4L /w standard bore /w full copper headgasket
Arp 625+ head studs
GSC R2 cams
PTE 6765 T4 / SS .98
Sheepey Top mount turbo kit
ETS 6" FMIC
AMS F1i intake manifold
Boomba 75mm TB
Aeromotive Eliminator fuel pump -10 feed/return lines /w custom surge tank
ID2000
Tephra v7 speed density /w ecuboost

wastegate pressure around 25-28psi:



42-43psi:

Holy hell that's a ton of power! Nice job guys!

Would you say that slight dip right after 7k is caused by the low end bias of the GSC R2 cams ?

Very impressive numbers here.

The dip up top around 7K is from the RPM tach signal getting lost.

The actual natural dip in the entire band up top is in my opinion definitely cam related to an extent. It should have S3's not R2.

The vehicle will lose low end with S3 though.

That is some great power w/ an older turbo setup,congrats!

Wonder what a 6870 would do? its a direct swap?

Managed to pull of a 10.63 at 149 with a 1.9 60' with NLTS not set up. Couldn't get it to get out of the hole on my Hoosier drag radials. She needs slicks ASAP. Thanks tom for a great tune.

So would you say that the R2's are done at about 7500rpm?

All of it.
It'll go quicker with NLTS set up so I'm not falling out of boost every gear shift and it needs slicks bad! I had waste gate pressure in first at 28-29 psi and it was blowing drag radials off like no tomorrow. Tire psi was 18 front and 16 rear. Launch control at 5500

with 780-800WHP in my old 2.4 setup I went 148.14. Definitely more in the car.

and my back half pickup was 44-45mph. As fast as the 8 sec guys.

Its possible at the track the boost is not as high as it is on the street. Keep in mind, at the track were starting at a higher RPM off the launch. There is no loading up at low rpm or really spooling when done right.

Also if it needs boost off the line or anything let me know we can make launch maps that can produce up to 30psi. These require good suspension & crazy tire grip though.

Also we fully support and use the 7 bar omnipower now so if you feel you need more resolution on the map sensor let me know.

Nice numbers, I'm surprised to see the 2.4 wound out to 8500 rpm. Is this a LR ?

I'm helping a friend put together a high comp 2.3 with Tomei solid lifter cams, 100mm billet crank, Manley 10.5:1 Extreme Pistons with a GTX42 turbo, Jack's built transfer case and Drenth sequential transmission.

Interesting to compare results.
