I don't know what dyno you're using but noticed the baseline numbers were like 220 something. Just wondering if you could elaborate further.

They use a Dynamics dyno... go to post 278 in this thread

It was 225-230 for base dyno with only gen2 stillen intakes. After c2cams, gen3 stillen upgrade kit, Motordyne lth, hks exhaust, ecutek tune it made like 297 so roughly 70 whp. I only have the paper Dyno, but they should have a PDF of it.

Hey,

What Chris posted above is spot on, the car came to us nearly stock with Stillen Gen2 intakes.

We added:
C2 cams
Gen 3 intake conversion
Motordyne LTH
HKS Hi-Power Exhaust
MA-Motorsports tune using ECUtek

Baseline was 229hp when it came here, left with 297

Car was a 2010 G37 7spd Auto

Thanks for the digital Dyno printout. I've got a few ideas for the future for the car, I will give you a call soon to update you on the car and discuss future plans for the car.

Thanks again

Is this your car? With the Motordyne LTH's, test pipes I'm assuming?

Wanted to check back in on this thread now that the car has been on the track for a few sessions. I was sharing the car with a friend in beginner so the car go some major abuse over three days at Gridlife South.

My first impression was of how much more usable power the car makes. I am shifting much less at Road Atlanta with no FD change and an increase in aero loads. I have all but stopped using 3rd gear when I have a clean track. The one exception is T7. With a couple good runs through T6 and T7 I was able to consistently reach a top speed of 155 mph at around the 300 foot marker going into T10A. There was another 370 running a different group saying he was only able to get to around 130 at the same point so there's definitely a significant increase in usable power. Still hoping to go to Z1 sooner than later and put it on their dyno for NASA classification purposes as I don't have a dyno locally to me that has ever had a Z car on it.

On a side note, the sucker punch oil pump handles many runs up to 7900 RPM without issue. I was not able to get my pressure gauge in the car before the event but I have another track weekend in September and I hope to have my gauges in by then after I sort out some heat related issues with the rear brakes.

Holy **** you hit 155 on the back stretch. Wow. Yeah I only manage to break little over 130. With a slipping clutch

Question for MAMotorsports does the C2 cam make power past the 8k mark?
or have you not taking any car past that point yet

Based on the results of my car it is likely the cams themselves can continue to make power past 8k. Unfortunately, there are multiple issues in the VVEL system that need to be taken care of first before you can safely rev the heads past 7900 RPM. The rod bolts also become suspect above 8000 RPM so it is best not to spin one that high.

That said, I am working on getting the parts needed to safely increase the rev limit but the parts for the VVEL system do not exist at the moment. MA and JWT are working on this now.

1slow use BMW m5 rod bolts to rev to 8,200. Don't know how reliable it is at that range but the car is still on the road.

Thee are nissan rod bolts available that will do the job from what I have researched. That's no issue. I'm just not going to rebuild my bottom end until we can continue the work in the heads.

hopefully they will have something by next year..i was planning on doing this in April or May..but i will delay if needed.
thanks for the info..hopefully Daelen from MA can comment on when they think they might have the parts available

As of before Daelen left for vacation there is no current ETA on those parts. I check in on that probably more often than I should lol. There will also be a little bit of a learning curve and experimentation as to if one part will fix more than one issue or if it will require something else.

As far as I have found and they have told me, no one has rev'd these heads over 8k safely for any length of time. Will be fun new territory when the parts required change sorted out.

Valve float issues on the intake side
