Our customer Superscout03 decided to get a 2.3 L stroker in his lovely Evo IX

This presented a great opportuinity to test and compare the Stage IV Evo IX with Buschur Gt3065 Turbo Kit pump with Aquamist

2.0 L stock

compared to

Dyno Flash built 2.3 L with Buschur Pistons and Pauter rods (balance shaft delete)

both graphs are with stock ecu reflash tuned at 28 psi




The stroker really works well on the Gt3065 - up to 7,500 there is no loss in power only gains - it really spools up hard - great for a road racing application

 

impressive!!

 

Wow do you have a video of that. Looks that it makes almost the same peak power but the torque and amount of spool it gained is insane.

 

those are significant gains in the earlier rpms!!
I think the stroker w/3065 is one of the best street setups you can have.
I miss mine

 

Was there something wrong with the car when it was brought in? Thats a rediculous gain in spool and looks as if the car wasn't making full boost until almost 5500rpms before the stroker. Shouldn't the 3065 reach full boost 47-4800rpms on a 2.0?

 

yeah, it does seem odd that it took a 3065 until 5700 to reach full boost

 

That seems to be a great turbo

 

nice post!! im glad that you guys decided to do this first before the rest of the work was done. the progress of his car from the stock 2.0 to the built set up will defintiely help me out and by doing the comparison with the 3065r first is everything i could have hoped for since im thinking about getting the next upgrade that he is doing (which i wont say as im not sure if he or you want everyone to know yet or not). when do you guys think you will finish up all the work on his car (pm'd him a couple of times and he told me what was going to be done)? those are the results that i am anxious to see!

 

I realize that it's outside the scope of Al's test but I'd like to see the 2.3/3065 compared to a 2.3/HTA 35. My only qualm is as to how much the more restrictive turbine side of the 3065 impacts negatively on power output above 5500 RPM in comparison to the full house 35. Back pressure is not where it's at on a stroker. The HTA 35 is just such a nice turbo and on a stroker should spoolup really well without the tradeoff of increased exhaust backpressure. I used to lust after the 3065 until the HTA 35 came along.

 

Nice that was fast , making great power he should be more than happy I bet

 

I'm loving that torque difference with the stroker motor.

 

what did he make for power?? cant really see it to well.

 

514WHP 476 TQ

 

You know I sort of thought... probably mistakenly seeing your post now... that the GT30 and GT35 turbos shared the same turbine housing and just had different compressors. I guess I was wrong.

After seeing results like this, I wonder where are all the people who answer 2.0 liter in polls are?

It's always been true I thought that there was no change in peak power but more torque and earlier spool.

 

yea sick spool
