Lola, speaking for myself, I'm glad to see you here. This is the kind of positive effort I hope for when I come to these forums. With the advent of the EFI Dude and being able to download new tunes and tweaks, I think now this S/C system is getting into the realm of Best In Class.

For those of you thinking about adding a meth kit to your car. We ran several dyno pulls yesterday with various meth spray nozzle configurations in order to really find out what works and what doesn’t.

All pulls were done with a malfunctioning intercooler (water pump works fine but somehow there is a water flow restriction problem somewhere around the two front mounted radiators). I’m going to work on that issue today. Also, all dyno pulls were restricted to 8,000 rpm. I told Cam that I was not interested in running the engine up to 9,000 rpm since I had a three hour drive back home and did not wanted to risk it.

Here are the findings:

1st pull (meth off) 283 whp
2nd pull (meth on) with a 225 ml nozzle before SC and a 100 ml nozzle after SC 268 whp
3rd pull (meth on) with a 225 ml nozzle before SC 270 whp
4th pull (meth on) with a 100 ml nozzle after SC 273 whp
5th pull (meth on) with a 100 ml nozzle before SC 281 whp

Bottom line:

The best pull with the meth kit on was the one with just a 100 ml nozzle before the SC (located just after the throttle body).

There was a decrease of 2 whp with the meth kit on but keep in mind that for the most part meth will not increase hp but rather assure no (or decrease the chance) of detonation and will buy peace of mind when pushing your FI system/engine to its limits.

Also, my current A/F ratio is very conservative (I can't exactly remember the numbers) and there is a lot more room for improvement. I do now have an EFI Dude and after (hopefully) I get done today resolving my intercooler water flow issue, will take the car for a drive and will post a couple of graph with my A/F ratios later today or tomorrow.

Does your car have a wide band gauge or are you getting the A/F ratio from the ECU?

Hey Bastage....pls put this in the HAWT GUY THREAD!!!

Juan, please follow-up with Bill regarding my recent conversations with him on the I/C. My second proto is being built right now and when it fits like a glove and Bill flogs it for me, I will go to full-scale production with it.

The dyno measures the A/F ratio. BTW, I would have called you, but it was a last minute decision to go on our part. We DEFINITELY have to have some kind of SC reunion somewhere, preferably a track.

The best part is, they are good people. The kind of people you can have any kind of conversation with for hours and hours and not realize you've been talking for hours. Just as importantly, they're the kind of people who don't say things during those conversations (technical or otherwise) that make you think they're completely full of themselves. They're also the kind of people that go out of their way to share information and don't try to cover everything in a shroud of secrecy.

Very classy people (and products).

I do this all the time, and it doesn't ever feel like it's going to bog. In stop and go traffic, this is a must. Gently letting off the clutch and letting the car smoothly move at a couple of mph seems like a feature that should have existed from the factory. Being able to smoothly cruise at 30 mph in 6th gear is also great (at 1500-2000 rpms), for those times where you're on a road that you wouldn't dare to speed on (roads with speed bumps/school zones/neighborhoods/in front of police stations ) and you want to save a few dollars on gasoline.

My N/A version, even with a light fly, has always had great idle control. Living on a dirt road I can't drive any faster than idle. I have idled in 4th without trouble. At extremely low rpms, though.

If you want to get better gas milage, watch your boost guage and try to keep the vacuum as high as possible(ie..further away from WOT). Doing this I was able to gain an additional 50 miles to a tank.

Juan--sweet info and JUST what I needed. Very close to installing mine---trunk mount 7 quart tank. Did you have to drill the pre blower spot or was it just a match. Where did you go with the power brake vacuum(the blower vacuum line?)
I rerouted my a/w cooler hoses to they are now just in series. I did this to make room for the rb air duct---works well and it seems that the intercooler in working great. It takes me a WHILE to warm the car up sufficiently to push her a little. 8K is my redline also.
My innovate LC 1 wideband SUCKS. I VERY carefully mounted and calibrated this thing and it worked for 1 1/2 days and DIED. No power--- cant do a damn thing with it. Tried it all. Their forum is full of problems with it--no more innovate for me --if it is this fickle---nope---i will do something. else.
Good point on the dyno----we are not tuning for the w/m system--it is for protection. Are you still running a cat?

oh by the way do yall know lolas car weights only about 1600 lbs and has well over a ton of downforce---at speed it could drive upside down. AND you ought to see his rotary powered go kart. but look in the back and you see the computer...........

I'm pretty sure that if you go thru your back order notes for the the I/C you will find my name pasted all over.

Where did you go with the power brake vacuum(the blower vacuum line?) NO See pix below

I would like to know the different intake temps based on where the meth nozzle is located.

Here is a sample of a WOT taken this evening after resolving the IC flow issue.

That's with methanol right? Good stuff.

Juan was that with both nozzles going?
What are your w/m settings on the controller box. maf 3 to initiate?
I am actually things of using the vdi activation trigger the pcm has to trigger the w/m at 100%--but I am not sure yet. Advice?
Great info man---thanks
