Fast90 joys

[ringram]

All done, not without some loss of blood however. Had to remove rear engine lift mount and space out the front one to clear purge line.
Started and idled fine right off the bat. Not noticed any extra power yet. Im sure Ill have to recheck my VE though. My air filter is filthier than Tordne's mind so that will need a clean out too.

Good luck cleaning Tordne's head.

If you have the means, compare your left and right bank AFR's. It wasn't until I installed the second LC1 that I noticed I had a severe intake leak. I got the worst of it fixed up, but something still isn't right.

Bloody hell, I just saw this

Man my air filter is black as! And it is a PITA to get out as well being behind the front grill, that I had to bend the AC radiator to get it down there .

Don't seem to be dropping any kPa though which is good, still hitting 100-101 no worries.

Yeah thought you might like that comment mate.

I was down about 3 kpa with the LS6 intake and had both banks STFT exactly the same, so will see what happens with the Fast.

Seems easier to hit atmospheric kpa now. g/cyl is nice, though my bloody scan tool hung so I lost my mega WOT runs, but not before pasting the BEN's in. High RPM/Load cells were +ve, like up to 5% so who knows. BEN's are always fun and you can chase yourself for the last few %. Mr dyno will have to tell me whats changed.

If you have a leak free (external and internal) installation you can expect some good results. Depending on modifications ~~+20 hp in upper rpm range is reasonable. There are many devotes in the Colonies. Keep us informed with your progress.

Definately likes to rev now. Used to run out of huff before. Now it runs to the rev limit, Im shifting faster too. So Im assuming its faster. Feels much more eager. Im not sure if Ive lost any down low, Im hoping Ive just gained from midrange up. Ill get a dyno overlay.

I'm glad it's working out for you. I wish I had your luck with it.

Update for anyone interested. Prior to the fast90/90 I had an LS6 and stock ported TB. I could never beat tordne's 0.86g/cyl even with my heads and cam.. My previous best was 0.85g/cyl

Well today I logged a nice 0.95g/cyl with the fast90/90 so its definately a worth while mod, and I can probably say that dispite people saying the ls6/tb are good for up to 450rwhp I recon they should be replaced well before then.

Edited to remind people this was done under test conditions so please ignore the VSS (lucky you didnt see the next higher VSS!)

Amazing what people can do with Photoshop

Since I rescaled the injectors based on actual fuel pressure, and being summer and all. I've been lucky to hit 0.80 g/cyl
