After many hundreds of passes on this completely stock RB25DET, the inclusion of a cheap, stainless exhaust manifold (which in hindsight, offered very poor boost control), killed the motor with a big lean-out. The added gas flow from the Nitrous couldn't bypass the back of the GT35 quick enough and the motor saw 29psi peak on top of the 100hp pill.

Best to date is that 12.0 :D

The short time and slowing 330ft time on the pass it let go on says that it was more than a second quicker than that but until it runs a full pass it doesnt mean anything.

The quickest the car has been was with the old std turbo, manual, nitrous setup - 11.662 @ 118mph

    • Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
    • Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
    • @KinkstaahKrinkle paint the "silver" alloy, not the red filter frame Engine bay heat won't be a issue worth worrying about as the silver alloy blocks it off on 3 sides, as for the top, the bonnet seals most of it and the big OEM CAI intake snorkel is still fitted in its original position  I will head into Clark's Rubber when I have some time to grab some pinch weld to tidy up the alloy after I paint it As for performance, I honestly wasn't expecting any, the only reason I got it is because the intake noise sounds cool to my old ears when I'm feeding it the beans Sometimes it's the silly things you do in in life that gives the most fun, and I do love anything that makes cool car noises In other news: I survived 4 nights at sea with Jackie not throwing me over board, holidays are continuing now as we are currently chilling at the Beachcomber in Toukley, after taking the coast roads from Sydney in the MX5, top down all the way, Toukley is where I spent a good deal of my youth holidaying during the summer months, there's lots of reminiscing going on,  and lots of beaches and old houses to visit Next on the list is to head to Batemans Bay for a few days, but we will take the Commodore out to stretch its legs, then Commodore hasn't really moved for months
    • There’s probably people who’d like to do it and then when it comes to putting their hands in their pockets they’ll all disappear into the shadows 
    • interesting....sounds like the later trans has software differences (or AM vs JDM). If I wasn't going down the tuning route it would be worth looking into retrofitting a new computer to the old box.
