Does anyone have this on an 05 evo. I'm having clearance issues with the Down pipe clearing the starter and the cusco lower tie bar and brace. Anyone else have this issue yet or no.

 

I was thinking about getting a ATP kit (haven't decided which gt35 or gt3071r), and since stock exhaust manifold isn't the best for flow, thought about going with a stock replacement manifold (say, Borla for example).
Does anyone have a ATP kit with a stock header replacement setup? If you do, what kind of header are you running?

 

AZ3AR had an ATP kit with an ssautochrome manifold. Imho the stock manifold isn't a restriction for the 30r and the 3071. It might be for the 35R though.

Well guys sorry for not posting my dyno numbers after getting turned. I was going to wait til my car was fully tuned. After getting a few PM's asking I tought I just go ahead and post them. So after only 2 hours of tuning most just getting the car to run right with the new injectors this is what I got. I made just over 370whp and 300wtq on 93 octane at 24psi. I'm hoping that with a few tweeks to the car and some more time on the dyno I'll get around high 380 to 390ish on pump with around 450ish on race fuel. The problem I'm having now is slow spool. It does not start to spool til about 4500rpms with peak tq around 6100rpms. The people at ATP seem to think it should spool about 1000 rpms sooner with peak tq somewhere around 5000rpms. I guess time will tell once I get it to the dyno again.

 

Are you saying that it doesn't even go to positive boost until 4500 rpm? Or do you mean you hit 24 psi at 4500 rpm?

 

Sorry what I posted was not clear on that. It does get positive boost at around 3200-3500rpms but at 4400 its only at 8psi. then from 4500 to 5100 it jumps to 24 psi. What I ment was you really dont feel it boost til about 4500rpms.

 

What gear are you testing on, first I hope with that kinda lag...

 

damn, on my atp 3071r, I'm at full spool by 3300rpm... do you have your cat still on? with the cat i fully spooled @ 3900-4000rpms...cat delete pipe=3300rpm full spool for me. 392awhp @ 21psi on 92 octane.

 

Do you like your apt...... Who tuned it for you.....Where did you get your turbo at....

 

The kit comes with the Turbo. ATP has a proprietary hotside that lets it bolt right up to the stock exhaust manfold. If you buy a turbo elsewhere, you'll still need their hotside.

 

Hey guys, I just finished installing my ATP 3037 .82A/R with 720cc injectors. Still in the process of tuning then will hit the dyno. My main complaint is the way the downpipe is routed, it rests up against the oil pain and makes some uncessary bends that my Perrin didn't, and I also had to take off the lower braces. A little bit of lag, but not too bad. I think it's around 1.5bar at 4500 rpms and holds strong. I'll post some video clips once it's tuned.

 

any update? I'm really interested in this kit.

 

I will have dyno numbers for you people tomorrow on the ATP 3037S with .82 A/R

 

bump!

 

Can someone host this dyno sheet? I made 370whp and 340ft/lbs of torque with about 11.5 A/F ratio on a Dyno Dynamics Dyno. This is done with the ATP 3037S kit with the .82 A/R at 24 psi on 91 pump gas. According to Richard from DynoComp that is about 502whp at the flywheel.
