M370 or some pulleys?

docaam · 03-19-2011, 01:18 PM

I installed UR pulley, not sure if that thing provides gains but rev feels smoother.

M370 is the key, even after full bolt ons it really made good difference across the whole band. I will say totally worth the cost

Appreciate all the input

Better to get the kit, it was about $230 with shipping included, alternator/crank pulleys + Belt. Mike@NST is a great resource and provides great service.

I also did the UR pulley, didn't notice a thing.

and my results on the M370 today were pretty lackluster at this point, so I would say pulleys.

I was above the curve on torque and hp in some places and below others, but never really had probably more than 2-3 hp or lbft difference in the before and after today at Z1. I'm gonna have the car retuned there after my next track day and we'll see if that makes any difference, but at this point, I'm not too impressed with it. The only benefit is it reduced the drone at 2800 rpms. Other than the M370, I have Gen 3s, test pipes and invidia with a Z1 tune.

I got my dyno done today after installing M370, there was a gain of 8whp and 16Nm torque

^^^ tuned or untuned?

Tuned, baseline is with Tune/CB/ART/CAI/UR Pulley

Jordo! · 03-21-2011, 07:59 AM

That's a good gain.

Hmm... I need to carefully examine other dynos. This is looking better and better as a future mod to me.

no its 269, according to them their dyno takes around 30-35% as drivetrain loss

Doccam, do you have a baseline stock?

I'm still a bit wary about aftermarket pulleys. Nobody has had them on this engine for a significant amount of miles. IMO, your car could be fine... Then again, it might not. I'd love to hear from N/A people that have had aftermarket pulleys for 10k + miles.

As for the M370, it seems hit or miss. That's a lot of $ for something that may or may not give you gains.

BLM · 03-23-2011, 10:52 AM

I think the M370 is almost not worth it without a tune. With full breathing mods and a tune I think it's totally worth it. Direct bolt-on and costs about the same as a Stillen G3
