Thread: Safe max rev on SRXXVE cams

If you have a divided turbo manifold and a decent turbine housing, the sr16 cams will be way better. I.E. if you kept your GT30R and got a .82 divided, then yeah, you will make 530-550whp and have full boost at 4-4500rpm and peak power at about 8500rpm

According to what snikers said, if you are only revving to 8K on a VE with N1's, the stock s/r's seems like they would do the job. What are the strength/rating difference with the stock s/r's vs the aftermarket s/r's? I still see the point you guys are making though.

97se-rblown - You running BC2's? I'm currently running them on stock s/r's on my daily.

Since I am at high altitude I am looking for about 460-480whp max before this turbo can't keep up. Guys are getting about 550whp at sea level. I have been the "big boost" route and now I would like to take the honda route for power. Low boost, high efficiency, high revs. But I still want it to be a street car. I am hoping to get the power I want before 9K, while having tons of midrange power. I want to be able to take a C6 ZO6 with ease on the strip this season.

I am looking for tons of power on 22psi of boost or less. What kind of torque numbers do you think this setup will see? 400wtq?

I don't think he meant the N1 cams, I think he meant the plain sr16 cams up to 9k.

The n1 cams would be insane! But I don't think the power would come on soon enough. Perhaps the 20V/N1 grind would work well if someone made it?

^Aren't there two different aftermarket sets of s/r's? Do you have links of both? Are they interchangeable from DE to VE?

Mazworx, BC and franklin all make S/R combos. But I think the Maz stuff is BC?

DE stuff can't be used with VE.

Mazworx is supertech stuff. They are the niceier then the BC but you do pay for them.

Mr-4Door-Sr20de You can run them with out s&r but I was planning on doing a 100 shot on the car with a 8k rev limit and thought that it would be some nice insurence to have them.

^Ok. I gotcha now lol. I don't go pass 7300-7400.

The N1 cams will work with a turbo setup but ONLY with a larger turbo. The N1 exhaust cam has so much duration and the exhaust valve opens very early that they will only be beneficial at higher RPMS with a larger turbo. The N1 intake cam is ok and could be run though.
