Finally got my scanner working with vista, so I thought I would share my boost chart... I have posted my dyno sheet before:

APS TT - base kit
APS Extreme Fuel system
APS 3.5" Dumps
APS 2.5" exhaust
Forge Actuators with Red Springs
GTM spec arias ED 9:1 pistons - 0.02 ovebore
GTM spec FI cams
JWT springs and retainers
Eagle Rods
Crawford Plenum
ATS twin disc with 1350kg pressure plate


Again, ignore the spikes. The dyno was putting in those anomolies for what ever reason

 

Looks good Ziv! Based on those graphs it looks like the car will deliver some smooth power, also has a very nice steady boost curve.

Hope you enjoy the car, I know its been a long road...

great numbers ziv!!!

 

Thanks guys. Like I said, I posted the power numbers before, but got the boost chart scanned up and people to seem to have interest in that. That is why I posted again

 

I am at work and can't see the graph right now. What are the numbers??? This is the exact build I am comtemplating but with a JWT 700BB kit.

Thanks,
Mike

 

Excellent!! I'm very impressed by that boost chart!! Those forge actuators with red springs really hold high boost well! With my GTM stage 2 cams and Evo TT exhaust, I should see high 500 to maybe even 600whp... I can't wait....

 

The peak HP is around 550, Peak TQ is around 575
This is on GRD's dynapack.

Most notable IMHO is the way the power holds to redline. There is very little drop in power from 5000 rpms to redline; I would say the cams are the reason for this. The tq is a little peaky, but not bad considering the 2.5" exhaust and from my experience, dynapacks usually read that way.

This is on 15psi of boost. There is maybe a 1/2 lb of boost taper towards redline, but it has little or no impact on the power curve

 

There was definitely more power to be had if I wanted to push it a little harder. This is about 50 more hp than I was running previously and this curve is holding strong to redline. I really didn't go into the tune with any set goals in mind so we played it by ear. Originally I had thought about really pushing it on a race gas map, but this is a street car, and I am already beyond what I needed so there was no logical reason to try to push it that hard and risk the motor. The car was making good power at moderate boost levels and doing it on a 92 octane map, so that was good enough for me.

With a more agressive cam setup and another couple psi or so, 600 is definitely doable. In all honesty, I don't know if the greddy evoTT flows that much better than the aps 2.5". I would love to see some flow charts if any shop has them. That said, I love the split muffler look of the evoTT and it sounds very nice.

Good luck and looking forward to seeing your charts

 

One of the nicest higher boost APS boost curves I have seen. Looks like those Forge actuators and red springs did the trick.

Do you recall what boost you saw, with the boost controller off? Or is this WG pressure on the chart?

 

Very nice. Congrats on getting everything together. Nice power curve and +1 on holding power to redline... Something that only a handful of cars have managed.

 

Very nice, a bigger exhaust would probably keep your torque from dropping but hey it is a beast as it is.
