wow 440 RWHP

[Snakey03]

wow yesterday i installed a 2.93 upper and a predator tune by
James at RWTD!! i already had 398 RWHP with a 12" Powerstack
filter and a Magnaflow cat-back w/ 4" tips. now i have 440.35 RWHP and 439 TQ. but i think it is a tad lean so i need some
opinions on the A/F ratio. the dyno chart is on my web page

will some of you look at it for me??
thanks.....greg

It is more than a tad lean it is way lean looks like it is near 12.8-13.0 threw the entire run. I would get more fuel put in that car pronto and stay out of teh boost until you make sure it is safe

Looks too lean.

Should have gone a different pulley.

A different pulley? That's not going to cure his A/F issue. It's his tune that needs attention.

That's not what I was implying.

He shouldn't have gone with a 2.93. Unless he's adding a 4lb lower.

:lol:

This is off topic, but... I like your "supercharged" door sills - where'd you get 'em?

 

[Shanezam203]

yeah I like those door sills too. Where did you get them?

 

[Snakey03]

thanks guys the door sills are from UPR Products
how did you get the pic to show in your post i couldn't
finger that one out that's why i posted the link to my site
i'm not very good with internet stuff i'd like to add mods,dyno runs
and 1/4 mile times to my info on here but don't know where to start

sorry, not trying to steal the thread........but where did you get the custom "Cobra Terminator" tags for the engine and console. Nice #'s! Get that A/F checked though, yikes

 

[HotRodHarry]

You just need to get that a/f in the 11.8 range...then she is good to go!!

 

[Snakey03]

the terminator tags were from a guy named gary loat from this forum

Sorry, but I don't follow your logic. Lots of folks here use a 2.90 or 2.93 upper only and make great power and torque, AND they're very happy with it. I had a 2.90" upper and made 457rwhp and 480rwtq. And I made a consistent 15 lbs. of boost with it. So I definitely would not have used a 4 lb. lower with my setup.

greg, your numbers look good, just add more fuel all the way across with the predator and do it on the dyno so you can see the results. good job.

HP looks good, but your torque is low for a 2.93. Should be up around 450-460tq. I have the same setup pretty much that you do and same tuner.
Probably when you richen it up, you'll gain the power back.

peace

If I were you, I wouldn't try changing anything without talking to james first. I'm sure his advice will be the best. After all, its his tune.
