Trying to figure out the highest Dyno numbers of a stock bottom ls1 with Stock GM Castings. My car make 448/398 on Serious HP Dyno here in Houston 2 nights ago. It's a Dyno jet. I'm thinking I might be pulling a record here. Here's the specs of the motor:

Stock bottom ls1

Stock 799 heads

Custom grid cam -
23x/24x .62x

Stock fast 90
92mm Nick Williams TB
LS3 Maf
MTI clear lid


1 7/8 headers
3" ypipe
Cutout

3.90 gears

3200 Circle D stall

Built 4l60e

Unlocked converter

LSX Power Tuning

seems high for stalled auto unlocked...if it were 6 speed numbers seem more inline

I made 400 RWHP in a c5 with just headers and an ls6 intake and a vararam, oh on a mustang dyno too. Don't put faith in dyno numbers.

^ a bone stock 2002 Z28 was before me. 6.speed. And made 298. So im pretty sure the Dyno was pretty on .

Go to the track. Who cares about the dyno.

Theres no secret to making hp on a dyno, thats the easy part. Drivability is the hard part to tuning.

I agree on that, thats right where it should be.

Please dont take my post wrong, I was not trying to knock your tune or that shop. I was just saying those numbers are not inline with with the hundreds of f bodys I have dyno'd even ones I didt tune. Are those numbers SAE,STD, UNCORRECTED?

I have the highest stock head, stock cam, lid/SSRA only, 2002 Z28, six speed, hardtop, owned by a guy named Nick dyno. These highest dyno/fastest quarter mile posts with intricate details are ridiculous.

Unported 243s are worth 15-20 rwhp. If you had stock LS1 heads your cam only dyno would have more merit but this isn't the case. I've seen one M6 car make 448/400 cam only with unported 243s and he didn't make a thread like this. Has this car seen a track? That will help your credibility significantly.

^ I was just asking questions, no need to freak out. And on old setup before the fast it's gone 11.59@119

Not freaking out but there's so many people that try to have record dyno numbers based off their unique build. Your track time is definitely solid. You should include it in your OP then people won't give you so much flak. If you do ported heads with the FAST it's definitely got the potential to be a 10 second car.

^ im going for 11.0 with new setup on motor and deep 10's on a 150 on a plate and 100 shark nozzle

Looks nice on paper but will it ET and MPH like 448rwhp? Judging by that you should hit 10s N/A if not it's done by a happy dyno

My car weighs like 3850lbs at 490 and sees 10.92 so you being less weight at almost 450rwhp you should be close

Will do! I'll be at royal purple here in HOUSTON. Putting my rear girdle/stud kit on the rear so hopefully she doesn't blow up on these bias plys lol

Would like to know numbers as well. If I wasn't working nights I wouldve met ya at the track in stay like 20 min away. Good luck!

Yea I would just guess happy dyno. Those are numbers I would expect from an m6 car. Tuners can only do so much to make power, its not like a ton of timing always makes the most power.

My little car did it. I put on some bias plys and it hooked ! Check out the time! A
