diamond pistons hardened rod bearings stock everything else in the block. GMR head, 78 lb supertech duals with Ti retainers, LNF Rockers, upgraded tensioner, four port single pass, tvs, 2.9 stock redline air box and filter, wrapped in silver insulation materia; zzp long tube header, egt probe .5 inch off # 3 exhaust port, trap door oil pan.

 

John I've been meaning to ask you about that oil pan... Made for track use or a safety gain for the street/strip as well?

 

John why did you put the EGT in #3?? Is that the hottest cylinder on a LSJ?

 

yes, well i only has 3.35" pulley m62 on it, not a 2.9 tvs :P

 

M62 goes for lunch at 6000 rpm and does not come back.

 

just curious,my 2.9 m62 hits 11 psi then right at 7400 hits 12.is this normal?

 

I bet its made for corners

 

kinna like this?

 

it is so. but if you brake really hard at 1330 you might need it. accel g is pathetic.

 

#3 or #4 are the troublesome cylinders. #4 its too difficult to package the probe around the t stat and the heater hoses. #3 does the job.

egt doesnt rise fast enough and afr the same to help you against runaway detonation on a turbo, but it is a useful tuning tool and an advisory that you are going too far one way or the other. I also enjoy watching the differences in egt according to air density on a day to day basis...

 

yea something like that.I shift at 7600 so I never feel it drop off or "run out of breath".

 

Are you sure? Or just never ridden in an lsj that doesn't drop off...

 

I've driven lsj's that drop off ,im taking about my setup and why it doesn't feel like it drops off.I've just noticed on lsj's I would usually see boost drop on the top end but mine rises.

 

Sorry I wasn't calling you out.
An lsj holding power past 7 is just nearly unheard if on the m62 unless you have a great head/cams setup and great cooling.

 

as far as I know, its not simply a case of adding cooling or a ported head or cams; the blower cant deliver; it goes out of its efficiency range as the revs go over 6500 . check the compressor map for more details?

 

A 2.9 at 6500 is completely off the map; nothing to look at lol
I understand what you're saying though.

 

^^^ lol back to topic, TVS thread.

 

so about that Eaton lol jk.

 

Anyone know of a totaled cts-v?

 

Sure don't.

 

I know a guy that has a CTS-V, and there is lots of snow on the ground...I could maybe convince him to take it out which very possibly could result in it being totalled, does that count?

 

You better show up with that TVS Redline at PowerCruise 2013! Just down the road from you.

 

my god he does listen!

 

^^^ lol at my mentor....

 

Powell, Bryan...

What are/were the EGTs you would see at the limit; gas vs e85?
