i was wondering what #'s should i be expecting on a dyno jet with the following mods. I live in SC so the temp probably will be 70's to low 80's.

steig iv port
6# lower
brisk silver tip plugs gapped @ 34
lfp idler kit
airraid cai
bassabi mid pipes
bassani catback
diablosport tuner

will keep you posted with the results

OK I'll bite...93 Octane 422/494 SAE street tune....

 

416 rwhp, 500 rwtq

 

I dont know about your part of SC, but I would expect the temp to be around 85-90 with ~90% humidity. So the #'s may be a little lower than you hope for. My guess...411/493

 

Depends on how aggressive your tune is. 390/450 on a year 'round safe tune. 420/485 walking the line.

 

Check the MAF voltage too....

 

im hoping for 425 and over 500

ive seen lightnings with just a 4# lower hit 400 - 500tq but its hot as hell down here so lets see how it goes

 

with a 6lb lower
exhaust, CAI

I have 419/545 on a dynojet
I have 375/485 on a mustang dyno

 

Do you have an upgraded Mass Air or mass air extender? I maxed mine out before I put the ported blower on.
Depending on your tune ~ 420/510 with a decent cool down.

 

I do not have an extender... I am still about 100 counts off the peg mark...

 

Well, just came back from the dyno and the damn temperature could not have been worse. the 70 to 80's I was expecting turned to 106 degress inside the shop and I didnt get the numbers I was hoping for but when it cooled down and I took it for a ride it felt totally different. Much lighter on its "feet". My tuner told me that with cooler temps i wil see more power and torque. I can wait till it starts to cool down to see what it has.Now i know there are some #4 lower lightnings out there breaking 400*500 but with the shop temp being so high, thats all it could muster,
tell me what do you all think.

The peak numbers were 410hp and 490ft.lbs. Like i said the shop temp was 106-108 degress with 60% humidity. I saw a peak boost of 16.23psi

 

Looks like I was DAM close in my prediction LOL. Good numbers for the heat though man..

 

You take 10 away here and add it there and WA LA
CONGRATS ON THE 400/500 CLUB

For those conditions you couldn't ask for more 04, You Did Good
and on a nice 60 degree night YOU WILL have more Boost, and Power, and SOTP

 

Yeah, my truck made 424/503 with a 4lb lower/Stieg's port/headers and a great PSP dyno tune.

Your numbers aren't bad for a hot shop. Get it to the track on a cool evening and see what it will do.
