is there no possibility that it is the tune?

 

Birdie..i feel your pain...dont worry about the numbers...evos are not the best dyno queens....as long as you like how its driving on the road...thats what matters

 

7psi increase and only 25whp. thats 91 octain for you... try adding some race gas before you spend the money on going with the meth.

the S1 cams are good to around 450whp before you should think about going to S2 or a larger cam.. your in the right area as far as the cam size.

also we should have a good comparison of S1 cams on the stock turbo on the same dyno in the next few weeks. and AMS is going to do a back to back stock vs s1 cams. i know Eric and Martin went so far as to reinstall the stock cams in the car so we can have an exact number as to what the cams do.

 

Greg is right, the cams do work and cant expect much from 91 octane. I also feel that I ain't giving this turbo a fair deal, so i'll let you guys know soon how it will respond on meth. Is there any local hardware store that sale 100% meth on the shelf?

 

great news greg...cant wait to see those numbers...
my cams are going in thursday and will have dyno numbers up by sunday max..will keep u posted..

 

I looked at the sheet. 28 whp gains peak and 20 ft lbs peak. 50 ft lbs of torque and about 50 whp gains in the midrange.

Seems pretty darn good to me.

Mr. Birdie,

First let me say I truly appreciate you buying our parts, really I do. So DO NOT take offense to the rest of my post.

This car is not set up how I suggest. It has no FMIC upgrade, no ported exhaust manifold and it is running through a high flow cat. I'd say the power you made on straight 91 octane is borderline GREAT!

Also, do you have an EVO8 or EVO9? If you have an EVO8 I am not sure why you made the cam choice you did. This is not to bash GSC but we have some other cams I'd have recommended, even though I admit I have NOT tested GSC's either.

I just know we can gain atleast 27 whp just from a cam swap on an EVO8 and that's with a mild cam.

Great results I think. 91 octane and cat with minimal mods.

 

David,
So you would recommend test pipe and FMIC and go back to the dyno again? I have a evo 9. What's the power difference with the test pipe and a HFC? I thought it very miminal when going from HFC to a test pipe.

 

Mr Birdie.

The offroad pipe on your car would gain atleast 15 whp, the car is making good power so 15 whp with an offroad pipe would not surprise me. Also the Race FMIC would gain a solid 10-15 too. The major change in your set up, stand alone.

 

David,

Can you cut me a deal with one of your GT30 kit ? =P

 

Mr Birdie, yes I could but that would be a horrible move from where you are. You need to finish up your mods first. What do you have an EVO 8 or 9? Look through Stages 1-4 and get the rest of those parts. Then consider an AEM EMS. Bring me the car and let me tune it. (Not that the tune you have now looks bad, it looks good actually) When I am done with it and it has the right recommended parts on it, you will NOT want a GT30.

 

david , Mr Birdie has and evo 9. do you think the new aem with mivec control is the way to go with this turbo? how much of a difference do you think we here in cali can see with the aem vs a flash?

 

I agree with david

California 91 octane is the worst gas around

Running a high flow cat with that 91 octane really limits your tuning threshold

I would suggest alcohol injection and a test pipe

It seems the OP's car would be closer to 400 whp with 93 octane and a test pipe which makes it a really fast IX

 

Honestly twostep just stop it man. Were here to advise others with their knowledge not putting negative comments.

I trust buschur product and yes I did know they ran the 20G-LT on race gas. I just took the chance to see if it can perform on just regular pump gas. Greg from GSC also have told me that it seem like the gas alone is restricting myself from making power. All the dyno sheet people have post on here in regards to the 20G-LT is on 93-94 octane on pump or higher.

I will contact you david in regards to a FMIC but i'm still debating in switching out the HFC to a test pipe. I'm also looking at Perrin Meth kit.

thanx david for the help

 

Hey if Birdie, if you go with that fmic, tell me how that works for you, what power you gain, and if you have significant lag or not..

 

That I agree, and the reason why I believe he sale product that work. That's the reason why I bought the TBE, LICP and 02 housing from them. I'm just curious on how many 400whp evo are there on 91 octane. I want to see because I saw some dyno graph off GT3076 turbo on evo 9 that only make 360whp and 350whp.
