What FMIC are you running?

Thanks for this answer. I don't have a good core so for the price of a 2.0 and Black Upgrade I'd rather have a 2.4 on Red. Seems to make more sense for my situation.

 

Freddie is running the Injen 3.5 FMIC. He will be going to the 3.8 Garrett core very soon

np, it is up to you what you want to run. a lot of times the extra 20% of VE that the 2.4 flows tend to make the Red fall on its face in higher rpms. Really depends on the fuel and power level. The Red on the 2.4 will have a decent power band till you break 550whp then it will start to choke up top. It takes a lot more to choke a black in higher rpms. If you look at my power band, it is still keeping up with the motor at 8500rpms.

If you go 2.4 make sure you get some large cams to compensate for the extra 20% of required VE. I had HKS cams prior to my Custom GSC cams and I realized how bad the HKS cams were choking my setup. below is a direct before and after of the cam swap. 150+whp at 8k rpms.

Josh, I just realized that I should have re-read my post above... There were a lot of errors.

 

WOW! The differences in the graph are from cams alone>>>??

 

Correct running the Injen intercooler that was on the car the day I bought it, however it is more like 3.2"... has been a good cooler for the most part, just outgrew it with this set up!

 

Yes, just the cams. All about the right combo man

Corrected that for you big dawg

 

I spoke to Aaron about their Cam specs thru GSC and he told me if I already had the S3's to keep them.

 

Amazing! I'm guessing cams on my setup wouldn't yield that much gain. Since I have a FP Red and stock 2.0. But it is def encouraging that cams open these motors up so much.

 

The S3s and my cams are fairly close... To my knowledge there has not been a direct back to back yet, but I would think power levels to be close. My cams have a bit more lift and a lot higher ramp rate which is great for spool and cleaning out the cylinders with fresh air quickly. If you noticed, when I went from the HKS to the my GSC cams, I didn't lose any spool... If I had done S3s the max power may have been close but I would have lost spool. I enjoy my cams.

Also Greg @ GSC has a hard time getting the blanks large enough to make my cams. That is why they reccommend the S3s.

So what cams would you recommend for a 2.3 + FP Black? I was thinking the s2's would do the trick. I'd do a 2.4, but I have some MIL.SPEC rods and MIL.SPEC 2.3 stroker pistons sitting in my hands...and they need a good home

 

alot of people that go from red to black wish they kept the red

i loved my red street monster!!!

 

Eric, if you do a 2.3 or 2.4 I would reccommend the S3s 100%. You are using a motor requiring 15-20% more airflow than a 2.0. So the larger the cam the better. The S3s on a 2.3 or 2.4 idle just like a S2 on the 2.0. Just to show you the VE difference between the two motors. Larger motors can get away with larger cams. I think an S2 is to small for a stroker. They are choking the motor in higher rpms.

hes like a broken record posting that supposed 150hp gain from cam swap. no where else will you find such gains. not even close. look up the AMS cam testing. from stock cams to the best didnt gain anywhere near 150hp. there was something amiss in his setup at the time.

 

Ok, for people who have run both a Red and a Black on a stroker, what are the differences in transient response? I'm asking because I know Aby didn't like the Black as much below 4,000 rpms. Wasn't peppy enough for him in day-to-day traffic on his 2.3.

 

1) First off the AMS cam testing was 3 years ago with old crappy cams! Maybe you should do some research and see how cams have changed over the past 3 years compared to those older cams. The old S2s vs new S2s are capable of making another 20whp and that is comparing two cams almost the same size. I like how half the time you never know what you are talking about.

2) The AMS test was on a 2.0 so a cam selction is completely different than a cam for a 2.4. Also the results between the two would have been much different as VE increases at rpms increase. The 2.4 increases airflow by 20% so with a smaller cam the VE of the head is dramiticly changed in higher rpms.

3) How dare you acuse me of lying or hinding something in my "test". I hid nothing and did nothing else other than changing the cams.

The larger cams on the same spike allowed the turbo to hold more boost out the top, if you look at the boost log. That right there is enough to show you how bad the HKS cams were effecting VE in the higher rpms.

Below is the dyno overlay of the HKS cams at 30psi. It took 5psi more boost with the HKS cams to hold the same boost out the top as the GSC cams. Even with 5psi less boost the GSC cams are 58whp more than the HKS cams made.

You always seem to be the negative pos that comes in to all the threads and starts shiz. If you want to start stuff with people you can do it on a different forum.
