Was wondering this the other day. I know the lsj doesnt really make much power beyond 24-25* timing. But whats the highest someone has had it to? I had mine at 25* with the tvs setup and was seeing 149* IAT2 temps. Just curious if anyone went higher, possibly with E-85.

 

ive went to 27 before and i lost power in places but gained it in others, ...... so i just made my wot timing to 26* at top end. It worked out great.

 

ssfamilywagon ramped his to 32-33 degrees on e85 at our dyno day a while back, didn't make any more power than the 25-26 surprisingly it didn't knock iirc. This was just a test for the dyno to see what happened lol

 

Hrm. I don't remember exactly what mine is, IIRC in the 27-28* range I think, but I'm on a TVS and E85.

 

32psi 43* 15.6 WOT AFR

 

u trying to blow it on purpose? lol

 

25-26 degrees while in High Octane Mode & CAM2 in the tank.

20-21 degrees on 93 Octane, no meth, no knock, 70mm pulley

 

You stop making real power over 27.5* of timing.

 

Yep in places.^^^^ u can gain power and lose some but it works out

 

hahaha no those arent actual numbers

 

im at 25. like mdub said max timing is really like 25-27 and i believe for e85

 

ive seen wut was best 25-26, i mena there are places where 27 could work for the good but say top end it wont do that great, itll cause more issues then anything.

 

yeah i thought 25 was the "safest" high amount

 

Think these are the numbers i got yesterday when i asked.

Meth:20-23*
TVS:23-26*
E85: 27*

Please keep in mind the are rough estimates

 

lol i run 25* and some places on my meth tune at 26^ and i got him the 310 on meth... so i think 26 wiht meth works fine.

 

Ive run up to 28* on the TVS on E85. Usually have it at a mix of 25* though

 

it next meth tune i get im gonna run 110* just to see if it goes kaboom.. jk

 

Im at 27* on E.

 

Not buying the second statement. Not in 3rd gear at 90 going up a hill. I tune too many LSJs in this great mountainous state to know better. Quit trying to sound like you can do something no one else can. We aren't stupid.

 

I'm not trying to sound like I can do anything, or that I'm better than anyone. That's my cars timing on 93. Period.

Others have gotten a bit more than me in the past w/o meth, and the blower I run.

P.S. I live in the mountains as well man.

 

IM NOT SAYING I KNOW ANY BETTER THEN ANYONE OR AM BETTER THEN ANYONE BUT IVE PUSHED 21* WITHOUT METH OR E ON MY OLD LSJ with a 2.6...... tune was 100% ve was to as well. ran a afr or 11.5 and ramped it to 11.8

 

is there a reason why it was your old lsj?

 

car got totalled from snapping a axel at 100mph.. can you say 15ft deep ditch!

 

4006*

 

hey man, was that the reason why i sold that block to you like a year and a half ago or wutever. cuz you ran that much timing, i mean holy crap ha ha ha ha ha
