Sorry for the delayed response, on the road this past week. To answer, a/f is shown on my charts. It's getting lean, but not critical. A tune will only help at this point, although it runs much stronger already. Since the a/f was monitored at the tailpipe during my dyno runs, and a cal factor applied to compensate for cats, I'm not positive the numbers are completely accurate. I have an ODBII tool coming early next week that will let me see what the stock w/b's think is going on with a/f. This will help me decide if I need to add an ems before I add hfc's, or after.

 

Ok! Has anyone done this to a boosted rev-up motor???? Looking for more power and TQ without up'ing the boost.

 

Not that I know of. But if you would like to try it, I can give you a $100 rebate if you can install it on the dyno and post your results.

Let me know if this works for you.

Any more dynos on a Rev Up with the Mrev2 + 5/16 spacer???

 

bump

 

Weaksauce. People will spend $600 on a piece, but not another $75-100 to see if it made a difference.

 

How about spending $1400 for an exhaust and saying "butt dyno feels good" or "throttle response feels much better" or even "engine revs up faster". All of these comments have been posted to express peoples' feelings about their fancy exhaust system (often with stock cats)

95% of people don't bother with any dynos, and of the 5% remaining, probably only 1% actually bother with a baseline dyno.

 

I'm very interested in the MREV2 and 5/16" spacer. Any more dyno results guys?

 

Oh well. I have a baseline. And one for my JWT. I'll probably try and re-dyno after each mod.

 

Can anyone give me a clear analysis of this dyno? I'm not really adept in reading these charts...such as, how much hp/tq gained, any loss, at which rpm, etc...thanks!

 

So are Mike and I the only ones to post a dyno of revup w/ mrev2 and 5/16 spacer to date?

 

If i ever have time ill get to dyno my car with the mrev2/spacer combo, but i wish i had a baseline.

 

I wish I had $600 to blow on it because I have a baseline.

 

Nice! I see you don't have that massive tq roll-off I had at the end of my run. I'm not sure what that was now, I attributed it the the V2 at the time but I just did some pulls on a dynojet today and didn't see that happen at all. I went for a hfc install and a reflash and didn't pull until after the cats were on, so either they wiped it out or it was just a particularity of the dynapack I was on. The car does pull strong through redline now, so I guess it had to be the cats. The reflash made it stronger up there, but the rolloff was gone before the flash.

 

......any updated dyno's or news on this?

 

Sup guys,

I just installed Mrev2 with the 5/16 spacer on my 05 6mt G35 yesterday... overall... i have very happy with the results. driving is much more fun now! car feels different in a good way and response is much better. check out the dyno. only mod I have is a Stillen Intake and Z tube.

 

So what are the actual gains in hp and tq ? Any loss at any point in your powerband? I like the feel of my revup all the way to 7k...not willing to trade for more tq if it means loss of hp up top...can someone shine any light on this?

 

The Gain is across the RPM range. from the dyno, it seems to lose a tiny bit on the top end, but as a daily driver, you would not notice the difference. but the gains through out the RPM is noticable. By all means, this is not FI or anything but this mod is great for daily driving.
