My 'vette is basically stock. Cold air intake and exhaust mod is really all. I have a 125 wet shot using TR6's now. Is it possible/advisable to run the 150 jets with the stock tune?

 

Yes you should be fine.

when i dyno'ed mine on the 150, we saw 3* of knock reported with 0* of retard. and that was all stock except for champion rc9yc plugs and GM red wires. i'm up to 200 now on stock programming. i now have the SLP airlid and QTP cutout. best of 11.97 @ 118 before cutout. 13.60 stock NA.

 

I do it. I've had no problems.

I use NGK TR6 plugs gapped at 35

 

I do it. I've had no problems.

 

OK, 150 it is then. Hopefully this will get me into the high 11's.

Thanks guys.

 

I went 11.50-11.60's on a 150 shot with only a lid and a catback in a '00 Z28 for reference.

You'll be fine on stock timing.

 

Was that on DR's or slicks? Stick or auto? Spraying out of the hole?

I'm trying for 11.99 with a 'run what you brung' setup. Whether this is realistic or not I'm not sure yer. I have Kumho non-run flats 275/40/18 and a RAM 402/980. I haven't raced the RAM yet but with the stock clutch the best I could muster was a 2.00.

 

I run 11.6s on a 255/50/16 DR w/the 150. 11.9s with the 75.

My 60' times are high 1.6 to low 1.7.

Lid,Cutout and converter.

I think Unit ran his time with the stock converter and Kumho tires (which is pretty impressive actually)

 

I ran 150 shot on my 2000 vette 6 speed with et streets all I have done is borla catback,4:10 gears,spec 3i clutch and k@n induction no tuning I went 11.31@122

 

none of you guys have had detonation problems....cuz im detonatin' like a son-of-a-gun!on a 150...even on tt still det or kr...it sucks!!

 

I did it and BOOM!

 

You could always put in a few gallons of 100 octane for peace of mind.
