Thanks to our customer Scott for the video footage and dyno charts.

Crower 272s on an AMS stage 3 car (reflashed) WITHOUT adjustable cam gears.

Proven, nasty power gains at an AWESOME price.

Before 330 WHP after - 369.5 WHP!

There were not torque readings due to some equipment problems. Another good install by the guys at Turbo Trix.

AFTER:



So anybody want a set of the magic bumpsticks? PM for pricing on 264, 264/272, and 272 sets.

 

why do the dyno charts look so different?

 

One's a HP & Torque chart w/ AFR and the other is a HP/speed chart.

 

thanks for the explanation

 

Sorry to butt in, but I do notice that the test conditions for the base run was 105deg F and the runs with the cams where at 78deg F. This is without SAE correction factor so the correction factor on both of those runs in the 1.03-1.04 range. I'm just bringing this up as I've usually seen 15-20whp gain with many different brand of cams on a stock turbo's EVO.

 

Crower are one of the few cams I have not tested, so I might try to get my hands on a set for testing purposes. Again, not trying to discredit the results, just pointing out the difference in the test conditions.

Regards,

 

I noticed the same thing. Evo gains a lot of power at lower temperature. 105 vs 79 degree is not a good comparison. My car made 340 whp on winter cold morning(56F). VS 300WHP( over 100F) on hot summer day. Normally my car makes about 310~ 320WHP.

 

Yeah, and the two dyno pulls were over 6 weeks apart. It takes less than 2 hours to install cams, why not just do a baseline before you change them?

 

Again, given to me by a customer, not done in-house. I agree the temp. difference is suspect, but I have another customer who picked up 33whp at Turbo XS (this is w/ a GT35R though).

These are great cams that are priced amazingly well.

Martin - PM me if you want to try a set.

 

sweet i am installing my cams in about a week or two.
crower 272/272

 

TTR has the magic dyno, I thought everyone knew that. Not to discredit crower cams or JSC speed, but TTR #s seem to be off more times than not.

 

Also, where did the tq plot go, how did it compare?

Apparently, they were having trouble with the dyno and could not do a torque plot; it's not purposely omitted.

Once again, these were given to me by a customer, not done in-house.

PM for pricing on a great set of cams at a great price.
