I was talking about E85 fuel with the SC anyhow.. and I believe he meant richer. E85 has 30% less chemical energy and a stoichiometric ratio of 9.0:1 so you need more of it. That is why you go with bigger injectors and a higher capacity fuel pump with that setup.

Why are you giving me basic info on running race fuel?

And why are you giving me info on running E85? I ran the **** in my Evo for 4 years and run it in my 13.5:1 cr Honda motor.
You do add more fuel volume for E85, true. It is still not necessarily richer. Stoich is Stoich whether E85 or petroleum.
I saw 70whp gain on E85 on my Evo because I was able to run a lot more boost (cooling affects as well as the higher octane). The stuff tuned more like C16 on the stock framed turbo vs its 105 advertised octane, cooling did help in this regard.
NA I use it because it is cheaper than race fuel. The gains were minimal even though I never ran that motor on regular gas. But comparing to other 1.8l motors on te same Dyno.

Sorry must have missed the E85 portion.

Very cool on the Honda. You ever hear of Force Fed Engineering? Ed Woosley is the man. Ive spend many an afternoon just listening to this guy. Huge knowledge.
This is him... The red car... LOL

Yeah, big gains to be had with E85. Cheap solution too all around. The problem is you cant mix it with pump like if you were to run MS109. MS109 also has better gains and keeping the boost lower. But from what I understand you wont run as cool as E85 so the gains are short lived.

I have heard of them, I think they're primarily a VW shop. That is a pretty nice GTi. I hear the VR6 motors take to boost very well.

The other problem with E85 is once you start nearing its limits as a fuel it becomes less consistent from batch to batch. I think there is a company who makes race grade E85 so it is exactly the same each time.

Before my supercharger, my SL63 already had the MBH Headers, tune, intake, and filters. Therefore, it was not stock prior to installing the weistec SC. The car dynoed 465rwhp.
After the SC install, the car made 603 RWHP. A gain of 138 on top of my previous mods.
This is what you posted.
I'm pretty familiar with the S/C set up and the cams. I'm also famliar with what Mike (Dodger63) has and I don't think he can get away with only a $15,000 investment at his level? I also don't think the stage 1 set up will get over 600rwhp?
Again, correct me if I'm wrong and I'm not encouraging either but I agree with Mike and the 120-140rwhp you are discussing is based on a "STOCK" C63, not one at the level Mike is at. Am I wrong?

You claimed that the 120-140 gain was achieved on a completely stock 63. Which is not correct.
There are other dyno sheets in this forum besides mine that had similar gains over their LT,intake,tune.
My set up is called the weistec stage1+.
In summary,
Whether your M156 is stock or not, installing the SC on it will net you 120-140 RWHP.
Got it?

Got it.
I thought when you had L/T, exhaust, etc... that was stage 2.
It takes L/T headers, exhaust, etc.... to get to the 600 number.
PLEASE don't misunderstand me, I think the Weistec S/C is an awesome addition to an already crazy powerful motor!!

You can say the SC adds X more rwhp on a car that has XYZ mods installed.
I could be wrong though. Id be willing to look at a SC install with no other mods showing 530+ rwhp. Is that data available?
