R2C, Stillen HFC & Stillen exhaust dyno pull

Red370 · 06-09-2010, 09:44 PM

of course on a dyno the intakes arent going to show high numbers, even with the fans, it will never accurately simulate the vehicle being in motion. Combined with a tune, the intakes, hfcs, and cbe combo produce a VERY dramatic increase in power, there are dyno charts all over this forum, guys with Uprev tunes, Cobb tunes, with said mods, with my AP, my inlet temps averaged between 5-8 over ambient, that in itself tells me that cooler air is getting in, which leads one to believe that power is being made. Lets not make uneducated assumptions based on the opinions of others when there are facts with results all over this forum gentlemen, use the search function.

Prolly not..too much work to do all that in one day - for me at least. BTW, on my way back from work with 79F ambient temp, I got as close as +6F on the intake temps. Not bad IMO. Sorry for the bad pic.

Okay, I put the stock intakes in my car and I will dyno the car with the stock intakes on July 17th at Forged. I drove around for about 40 miles this afternoon in 92F weather and the intake temps were about 8F above ambient temperature. The biggest difference I noticed is that while idle at the light, the intake temps do not rise as fast and become not as high as the R2Cs intake temps, which rose to 150F. Today, with the temperature about 10F higher that earlier in the week, the intake temps at the light after a few minutes rose to about 115F. The butt dyno did not notice too much difference, but the car is definitely a bit less loud.

take your rc2s with you and bolt them on after the baseline and dyno again

Exactly, unless you do a before and after the same day all you will have is speculation. If you are going to go through the hassle of another dyno with the stockers on, might as well stay around another 30min and do a 2nd dyno with RC2's installed for a proper before/after test

So far do you prefer the car with the RC2s or with the stock intakes? I ask because I am considering purchasing the RC2 intakes within the day.

The R2Cs are nice intakes, but I'm not sure if they gave me any gains. Maybe a few HP at top RPM. After I took the R2Cs out, I noticed that one of the seams on one of the heat shields was cracked. For now, I'm staying with the stock intakes and bought some HKS drop ins from AAM, and now some intake tubing from CorSport Inc.

So you're saying I should keep my $500. Gotcha, thanks

I had my car dynoed yesterday at Forged on the same dyno I dynoed it early June. Since the first dyno, I removed the R2C intake, put in the stock boxes, replaced filters with K&N drop ins (the HKS filters I ordered from AAM were on back-order and to this day AAM has not credited my $64 - shame on them! So I bought K&N) and got HFS post-MAF tubes. I also got a canned COBB tune for HFC and CBE. Temps were about the same; high 70s to low 80s, but higher humidity. Result: I lost almost 20 HP at about 5,400 RPM and about 10 at max RPM. In all honest - the car doesn't feel like I lost, rather with the COBB tune, I feel more torque, but that went down by 10 Ftlbs. With the COBB tune, the car has a better A/F ratio and fuel trim, so I don't think I can blame the tune for the loss. But I doubt that the R2Cs gave me an extra 20 HP, so I'm a little confused...car feels torqier, but numbers are down. I might throw the R2Cs back in and see what happens. I like the K&N Typhoons as well, so I might give those a shot, but waiting for some independent dyno results.

Too many variables to accurately gauge what is going on.

JvKintheUSA · 07-18-2010, 02:26 PM

I do not disagree with that ^^

I just put the R2Cs back in and took it for a spin - intake temps were same as with stock intakes while in motion, power and torque the same according to the butt dyno and A/F was 12.2 at WOT, so that looks all pretty good. Sticking with the R2C for a while.

Since you have them and they are not losing any power you might as well keep them on. But I think you have kinda shown that the short rams atleast are the same or worse than stock, so some can save some money if they are going to buy the R2Cs just for performance. Bling is another story.

^^That's the plan for now.
