GSR intake cam IS better for superchargers!! - Tuner-Junction

jadkar · #1 (**permalink**) August 14th, 2006, 06:39 PM

Just to let you know I swapped the ITR intake cam for a GS-R one this morning. I still haven't re-tuned, Jeff's gonna do that for me on the 28th. However, as a preliminary opinion I definitely think it's a better cam combo for my setup.
When I had ITR intake and exhaust cam my boost would gradually increase from 6.0 psi at around 4K to 9.5 at 8000RPM. I would stay at 9.5 until red line (8600). Now with the GS-R intake I'm not developing more boost but I'm developing peak boost earlier. In other words at 4K RPM I'm at 8psi and it jumps quickly to 9.5psi.
The dyno will be the judge but I really think I picked up more HP lower in the RPM range which will work wonders for the uphill at Watkins Glen :thumbup:

Special thanks to Julio for just giving it to me no charge!!!

midrange torque ftw

glad you got that sorted...your torque curve should be beautiful now

Yeah, it's all squared away. The torque curve was already super flat so now I can't wait to see what it's gonna look like!!

2 more weeks. Before I was running 8.0 psi and I was at 269whp. With 9.5 - 10psi and the new cam I'm hoping to be at 290whp. We'll see

that should be doable

If so I will most likely be the strongest SC 1.8 on the East coast. Right now LHT has the title with 281whp on 9.0psi

just wondering, did you ever post a dyno plot?

that brings up something ive been curious about and meaning to ask you on the board...
LHT makes their own SC header designs, but does the kamikaze outperform that?

I'm not sure, however I do know that Endyn (god of supercharger technology) uses Kamikaze headers that they port on their own setups. That's good enough for me.

eezeede - Yes I did post it , but just for you here it is again. Keep in mind this was at 8.0 psi with the ITR intake cam.

any reason youre not running neptune?

Hondata S300 > Neptune

IMO

ezeedee · #12 (**permalink**) August 14th, 2006, 11:02 PM

that is a nice torque curve. its like what, 75% of peak torque at 2k rpm

John you are going to be near 300whp....this time do some cam tuning as well..mgiht be able to get some extra ponies from it...

indeed, jeff has been getting some nice gains through out the rev range just dialing in the cams...i recall seeing one thing on his site where there was a 30whp gain off the cams alone (obviously on a highly boosted turbo car), but i think whatever you can get should be enough to bump it over 300whp

Yeah, it's strange he didn't tune my car with the cam gears. He tried for about 5 minutes and then gave up. He said he's not been succesful with SC cars and cam gears. However, John at LHT said he ALWAYS picks up about 5 hp from gears. I'm gonna lean on Jeff to try harder this time

Yea try to get him to mess witht he cams...or have him call john at LHT and have them talk it out with adjusting cams for SC cars..its a suggestion that might work..
