i've been watching your vids for a while, i believe you ran a 14.2 N/A?
That run wouldn't of been me and those vids wouldn't be mine, I've kept this thing in the dark for the most part and taken very few videos of her. I think I've posted a couple of early pics around the place though from a while back. There are some N/A alloytecs running low 14's though.i've been watching your vids for a while, i believe you ran a 14.2 N/A?
10.6??? was he on the bottle...That run wouldn't of been me and those vids wouldn't be mine, I've kept this thing in the dark for the most part and taken very few videos of her.

Quickest N/A LY7 over here ran a 10.6 or so but the LY7 was sitting in a very small/light car fitted out for the strip so I don't really count it... that had a custom intake manifold and cams and may have even been stroked from memory... That was going back a couple of years now. I can't remember the details but I think someone made a mistake somewhere and blew the whole engine up to the point where absolutely nothing could be salvaged. They never put another one together and havent heard of any other LY7's running those numbers whether N/A or FI.
Maybe... Couldn't tell you exact specs of the car or how they were running it at the time... The LY7 engine was transplanted into a very small and light car fitted out for the strip though which would've assisted a lot.10.6??? was he on the bottle...
Awesome info. Thanks so much for posting.
Are there any resources in Australia for the 5-speed that we have?
Simply put, the 5 speeds are still a drama for us... I elected to buy the 4-speed for a reason lol.Our 5 speeds will be the death of us lol
Not sure I buy into what you are saying.The only reason timing chains were stretching is because the oil life monitors on the car were too prolonged, and owners who didnt subscribe to the "oil change every 3000m/5000km" philosophy would run they're oil down to the 5% and further territory. This in turn would not provide proper engine oil performance and hence would alllow the chains to become excessively hot and improperly lubricated, causing them to stretch and or break. I believe GM offered a reflash to fix the oil life indicator issue.
Tech doc's for the tranny, and 4 GM service techs. I was told after 285hp the tranny wouldnt hold up. Thats why our torque management is so bad stock even with the 256hp going to the tranny on a good day might fudge it up. Dunno if this is accurate tho because alot of guys have there TM tuned down to 10% or lil more and there trannys run fine.who said this?!
This saw us make 337rwkw with 12 psi boost. I don't have the dynograph on me but this was made at approx 6200rpm producing 1150nm torque or so.
You're probably right mate, as you can see in my original quote above they are "approx figures" as I didn't have the dynograph with me. I'm geographically dislocated from the workshop at the moment but I will get the precise figures for you as soon as I can.1150nm = 848 lb-ft.
It really made that much? That power, rpm, and torque combination doesn't really compute...
