I never even realized that.

My car on the motor is 13.2

Add 42 more RWHP and 66RWTQ to the numbers I PM'd you earlier with the A/F on the 150 shot at 12.1-12.3 across the RPM range...

 

If it makes more power ther I'd run it ther for sure.

My 150 shot we run at 12.5 A/F .... you should be checking the plugs to make sure but 150 shot on a built motor is not much N20 at all.

 

Plugs are autolite Ar94's and they look perfect. I pulled all them and checked them over with a fine tooth and comb.

The car has no DCR either with the camshaft..

 

good advice from atv. should be in the 12's for sure.

 

hey man.... off the topic but i just got a 99 vette... how do u like the lg headers... and how were they to put in

 

What the hell do you know.

 

Most guys I know generally run 11.8:1 with the gas, and these are stock bottom ends. Some tuners run 12.2. I think this is a tad lean but as long as you pull timing should be OK.

If you can get it to sit on 12.0:1 nicely it would be a good mixture.

 

just as much as you

 

Do I know you?

 

Are you saying 12.0 is ideal or should most spraying 100-150 on pump 91-93 stick with the general 11.5-11.7?

 

Every motor likes something a little different but yes if your car like 12.7 to 13.0 on motor there is no reason a 150 needs to be at 11.7-11.5

My car likes 12.7 on motor and we run the 150 shot at 12.5.
Not saying everyone should do that but 11.5 is on the other end of the spectrum. You would probably never hurt anything with just a 150 shot with either tune up but your leaving HP on the table running it that rich.

 

Yes...yes it is!!!

I think he might of saved me from some potential problems that I know you guys had last year.

 

Mine N/A is at 14.7, when spraying a 125 wet it's at 11.6

 

HOLY ****!!!! 14.7 AFR N/A

 

Like the LGs, they went on easy and sound good even w/ stock TI exhaust. Not a lot of difference at idle or cruise but you know they're there at WOT. I don't plan on adding cubes or a big cam so I think streets were right for what I needed. Price was right too

 

your kidding right?????

 

are you talkin 14.7 wot? Mine runs about 14.6-.7 cruising, but 12.8 wot n/a. 11.7-11.8 on the bottle. If you are running that lean wot n/a, you must be running a huge fuel jet to bring it down that much on the spray.

 

I also wanna say 11.5-11.7 AFR on a stock bottom end. my stock bottom end lasted me more than a few years that way.
