Methanol/water injection

[BLACK 346]

That is interesting, I was of the impression that if you were up it for the rent and ran out of meth, bye bye motor, hence the warning lights that come with the Snow kits? Will have another chat with Brad prior to retuning.

Meth injection changes the AFR. Any tuner that tells you otherwise probably shouldn't be tuning your motor. If you're on boost and run out of Meth, the AFR will be lean. Depending on how much you're squirting in there and how far they're pushing the tune, it may be somewhat safe but it's a risk none the less.

Given the recent logs of fuel pressures (or lack thereof) and maxed injector duty cycles that I've seen from well respected tuners on supercharged motors lately, I would be checking and double checking everything.

It will be fine, one of the best tuners in the country has set it up & it's not a wild angry tune.

Got a call from Brad yesterday and the old girl goes in middle of next week to have the kits fitted, will post results on completion for those that are interested

A little off topic in my own thread, but whilst out for morning walk this morning we came across an E3 Clubby at the lights that had that real lopey tough idle (ie big cam). My wife made the comment on how good it sounded and can I make mine sound like that at idle (silly girl). I pointed out to her that my old VT sounded like that and I didn't think she liked it, her reply was yes I did, the VT sounded awesome. So long story short, how much of this idle is dictated by cam size and duration etc and how much is tuneable? My Calais only has what I would consider a small cam (VCM21) and has a somewhat loud idle but fairly tame ie no chop to it at all really. Can that be changed in the tune to a degree or would I need to go bigger cam?
Not real keen on a bigger cam as not sure how that would work with the blower, and is expensive exercise if I decide that it ruins the car? Any advice/experiences appreciated

Quoting myself here rather than start another thread. Is anyone running or know someone that is running the VCM16 cam? I have listened to a few sound files on the interweb and it sounds pretty good ie choppy idle. It is also marketed as a blower cam, so another bonus. Any other recommendations for a tough sounding cam that would also suit a blown car?
Cheers

A very good mate of mine has a VCM5SC on his blown LS1 stroker, it's a grind designed specifically for superchargers.

Actually I bought some performance gear off Matt at MRC Performance 2 weeks ago & he was great to deal with & had it couriered to my front door in under 24 hours.

Harrop make some great gear as well & are somewhat considered experts in supercharging.

The boys are very helpful, could be worth giving them a call and asking their advice.

Edit...

The H04 might be the one you are looking for.

That is exactly what I am after Ed. Thanks for the vid. I will chat with Brad on Monday and see what he thinks. Cheers.
ps...My blower is already a lot louder and tougher sounding that that vid lol, especially combined with the gilmer drive.

Edit: I wonder if my 2500 stall will cope with that cam?

I would talk to the boys at Harrop about the stall etc, they sell plenty of the stuff & have their own workshop & dyno for testing.

So does Brad mate. No point bothering a shop that doesn't know my car, nor will ever work on it

I was just suggesting to ask their advice because they manufacture, fit & sell the stuff so they would know the expected results better than anyone.

Rod another cam to look at is the LS9 blower cam, pretty sure IJ uses one in his 408 SC was in the tonner & now his racecar.

Even though that would be a great cam,


I don't think it would give a very lopey idle Mick.

I have read a few times from people whose opinion I trust that the BTR 3 TRQ cam is awesome for blown motors and can even get away with a stock converter!
