Nice Tomei is SUPER

 

The Tomei 290s would be IMHO a crap cam on a street and occasional track car... it lost tons of power under the curve... however for a drag only car, these look like they performed. I would venture to say that these cams would more than likely be crap on an OEM non-ported head as well, as you would not be able to take advantage of the benefits if the longer duration.

Car was running from the pump E85. All pulls were done at 20 or 21psi(I don't remember exactly which one).

 

Tomei not joking around 270 did hella good against the 272 line up!

 

How did you get these specs?

 

Nice to see my Tomei 270s over powered the S2 and Kelford 272s but I bet the torque down low did the same to both.

 

I bet the 290 tomei cams with a ported stock manifold would have been nasty.

 

As an GSC R2 user I'm biased but I'm pretty impressed with how the R2 went. The rpm range is huge, good max power at 8500 and max torque at only 6000, better than the S3's. I can also say, on my Mivec set up at least, they drive better than stock.

 

How often are you in 0C weather?

 

would love to see the s2 vs r2 comparison / overlay.

need to install my r2's!

 

You need to so I can see a "camparison" between the two... I have been contemplating making the switch but haven't seen anything near my setup so I am hesitant to take the plunge...

 

That is my car.

 

Sorry to hear about the engines that died, and the clutch that went while doing this cam test.

 

I wish they could do a 2.3/2.4 stroker test also. I bet the R2 would shine even more!
