TEK302

Against a L99 with LS3 top end conversion with nightfury cam, intake, header back exhaust, stall, dyno tune.

Here is my most recent dyno sheet.


Intake, ported throttlebody, off road h pipe, e85, lightweight flywheel

Obviously he would take me from a dig, but what about a 40 roll?

Buddy of his said he dynoed 460whp

I hope not. lol. What's the race weight of your car?

V8EATR

Eh, could go either way. Depends on his weight/tune.

More than likely.

TEK302

Its a 2012 boss you richard head... with me in it it probably weighs 3800lbs.

Love the average power from 6500+

just baing honest man, your STD corrected numbers are terrible. you are in the 415-425 range SAE. something is wrong in your setup.

TEK302

Don't quite understand. Are these not corrected numbers? I went to the same dyno when i was stock and put down 395.

How my car runs also say otherwise.

What kind of dyno did you dyno on?

TEK302

Dynojet

99whitez28

Yea something is way off.....any track times?

TEK302

A fbo 2015 made 442 same dyno. I dont understand whats wrong with my numbers

99whitez28

There was a dyno day i went to a couple of weeks ago and my buddies 2015 with full exhaust CAI tune E85 made 411...on the same day i made 417...You should be close to that FBO one you talked about. I would say you should be around 425 at least. MAybe closer to 430 on a Dyno jet. Get longtubes and full exhaust and be around 450-460 easy. Boss heads flow way better also

So FBO Boss's are Faster than FBO regular 5.0's?

TEK302

Im on factory manifolds. No headers.

Ive literally never seen any coyote or roadrunner dyno that high without cams

99whitez28

a buds 2013 gt just made 508 with Cams Cobrajet Full exhaust CAi E85 tune...he was at 464 before cams

I would hope so.

99whitez28

They should be just a bit. They have better flowing heads and cams so technically they should mod for mod...shoot the new 5.0s have Boss style heads with that flow. thats y modded new style 5.0' make more mod for mod against the older 5.0

The problem is that ALL dynojets read exactly the same. Oh, wait a min.
