Cam recommendation needed

Greg,
I met you at the Redline Time attack. My car was the silver 03 Tuning Technologies' Evo parked next to the AMS car. We ended up with second place in the Modified awd category. I'm looking for a little extra power, especially from 6000 to 8000rpms. I currently have a 2.3 AMS stroker motor and run a 35R turbo. I'm currently using HKS 272 cams. I'm about to try the AMS VSR intake and thought I might try a new set of cams to make the most of my top end. The one limitation is that I run the stock ECU and need good daily drivability. What do you suggest? I'm also looking sponsors, full or limited... We'll be competing at Buttonwillow (Redline Time Attack) in April and the 2007 EvoM national shootout in Vegas.

Thanks in advance for any advice given.

I can't answer for Greg, but I'm running the 280's on stock Ecu with EcuFlash. These should be comparable to the S2's as far as idle and part throttle driveability from what I understand in talking to Greg. I had to bump the idle up to 1000 rpm's, but with that change it idles fine with the a/c cycling on/off, or any other variable load like radiator fan cycling, pump the brakes, etc. It would stall with the idle set at 875 rpms, but does just fine at 1000 rpms. Part throttle driveablity is excellent also. The only drawback is I get a constant P0300 code, so it won't pass emissions till I figure out how to clear that up. Hope this helps.

He reccomended the S2's for me and my 3076/2.3 for road racing and daily driving. Effective duration is 272 274 I believe and they have greater lift than the 272s by almost a mm, I'd say they would be a good candidate for your setup too.

I have their(GSC) 272/264 set up in my Evo now but I just changed over to a 2.3 and a 50 trim. Curios to see what their recommendation was/is. Should I stick with the current set up or switch to something else?

Do you have the old GSC cams or the new ones?

From what Greg told me the new grinds are much better all over the powerband as long as you have the setup to support the flow. As I said I am running a 2.3 plus 3076 and he reccomended the S2's for me, they seem to be similar to the Jun's in terms of lift but they must have much nicer ramp rates than the other aggressive cams.

unless your made of money those are an absolutely rediculous choice. 960 british pounds is almost 2k

Have fun with your cams that could of bought you a lot more power if allocated elsewhere.

1st I'm made of money
and those are exotic cams which will give you tones of torque and they designed specifically for 2.3L
yes, UK prices are sky high, but you get a complete kit: cams, cam gears, springs and retainers.
one's you try Pipers, you can't look at anything else

It was good to meet you at Cali Speed way, and if i can ever help out let me know always glad to, our 2007 sponsorship and racing budgets are already set. Actually this year and 08 are set we have some very large projects in motion that will be in house. We are planning to work with redline to offer contingency for the remainder of the year.

The S2 cams are where you need to be. Your setup is the setup they were designed for in274 11.2 ex272 11.0. With the 35R a 2.3 and S2s you’re going to get a big kick out of them especially over the HKS 272s your presently running, you should see some serious gains 30-40whp at higher boost levels maybe more. Shouldn’t give up any low end power either.

As far as running them on a stock ecu, they will idle about as well as HKS 272s, those things are awful, idle wise compared to their power range. 1k idle and a little richer should be good to go. You will have to have upgraded valve springs with the S2 cams. Singles will work fine unless you feel like spending the money on duals.

The guys running the 2.3L and 50 trim and 3076 need to be in the S2 cams. The added displacement requires more duration than the S1s. I would suggest a switch for those running the older stuff if you want some more power. Now if the car is a 2.0L with those same turbos i would put a S1 set in.

Thanks Greg. I'll be getting on board S2s right away. No prob on the sponsoring thing, but since my car is currently the TTech shop car, maybe I'll get some sort of wholesale break from Alfred (he "pimps" your cams all the time, as they seem to make consistently good gains). I'll be sure to post up how they do (before and after) when the time comes.

I plan on installing the AMS VSR intake mani, a 65mm throttle body, and the GSC S2 cams all at the same time. Does everyone agree that these are complimentary mods? If Alfred is willing, we can dyno the car at exactly the the same boost and afr adding one part at a time to see the gains made... Alfred is soooo busy, but I'll try to talk him into it. I think it would be a very good test.
