in a lt1 car. minus the stall,gear which wont really effect hp. with or w/o roller rockers. but on a stock internal lt1 how much power is noted.
with or w/o injectors tune is a must i agree to get the most power.

 

A stall/converter does in fact affect hp #'s on the dyno

 

each car is different i have seen full bolt on and gear cars make high 290's and some make it in the 315-320 range with rr's

 

highest i have seen on here or anywhere is in the 320rwhp range

too me track times r most important...

bolt on only record is 11.80 set by shon herron

john p. (1slowformula) has gone 11.86

and a bunch of guys have gone low to mid 12's

 

I also say 310-320ish is about the max

 

Through an auto I'd think it'll be somewhere around 300. Maybe 310 at the most.

 

That'd be my guess. But, I'd say it'd be doubtfull to hit 300's with a stall and stock RR's.

 

it seems like its all over the place, i would hope to get at least 300rwhp once i get my LT's on and a retune, but i've seen this vid long time ago and wondered if its plausible they show no dyno graph.

300 is very doable.
I put down 279 with a catback, highflow cats and a K&N filter when I bough it a few years back.
Didn't even have a mail-order tune on it at the time.

Add LTs, a tune and you should have no issue hitting 300, even with an auto.
1.6:1 rockers and an EWP don't hurt either.




Now, if you're looking for speed ....
Drop weight wherever you can, all the stuff you don't need in the car.
(There's a whole list over in the drag racing section)
You'll need sticky tires and good suspension as well.

In the example above Shon didn't hit 11.80 with a full-weight car.
320rwhp will generally not get an Fbody into the 11s.
(At least not without dumping 700-1000lbs and a few traction/suspension upgrades)

 

302/321, M6 car, 1.6 promag RR, forgot which ones but comp cam springs, K&N CAI, bbk shorties, 3" catback, granatelli MAF, MSD 6a, trickflow ceramic coated elbow, msd opti and coil. Best has been a 13.5@104, with a horrible 2.2 60', only weight out of the car was rear seats/belts and spare and jack. No tune.

 

so if a car runs 13.47 at 104 does that mean its a 300 hp car at 3450lbs with 1.98 60ft.

 

With flowmaster catback, K&N cai, Hypertech chip. I trapped 105 on a 95 degree summer day.

 

I would say 280whp 310wtq. 300whp shoul get around 106 trap

 

because all i had were lt's,ory,full exhaust and cai everything else bone stock 3.23 gear and a4

 

yes I would also say 300 for an auto is a good number

 

That's about right. The LTs make a HUGE difference.

 

I did the numbers in the sig.

I have every bolt on except a ewp.

Mac mids
Hooker CB
crane gold 1.6rr
crank pulley
52mm tb
ls1 ds
1le elbow
airfoil
e cutout
no cat

and my heads and intake are gasket matched(1.5hrs of light work)

And it was on 18 inch zo6 rims with a 3.73 gear in the 10 bolt. I am throwing on a LS1 lid, mallory 685, and csi ewp, 30 lb injectors. Shooting for 340rwhp.

If you would like the graph post your email.

 

My best time was run in my sig. with full bolt-ons (stock rockers) & 4.11s at 2500ft. DA on a 2.00 60ft., i'm guessing my rwhp is between 280-300, this is at full weight with spare & jack.

 

Switching from 1.6 s/a Promag's to 1.7 Scorpions gained me 10 rwhp.
It put me at 309 rwhp.

 

now by putting in a 3.73 gear how much of a power gain can there be
