VE SS 6.2L results ... have a looksee ...... discuss ?!?!

[Lilsexc_]

Hi like minded peoples. I put my Baby up on the dyno at the end of March . The results are shown in the image I will be adding on here shortly . Not much has been done to the car from new . Since buying it , at this stage all I have done is install 2 1/2 " stainless twin exhaust . within the next fortnight , I will be purchasing the Pacemaker setup I have my eye on . I'm sure I will see a difference yet again . So please feel free to comment about what you see .... honestly I know a fair bit about cars , enough to service it myself , but the dyno chart well , I'm pretty sure I understand it , but I don't know if its GOOD or not .
Thank you for checking it out x

Unless you have done a repower, its a 6.0, not a 6.2.
Manual, or auto? Seems a bit high for just a catback, or a happy dyno.

A little on the high side ~15rwkws but a good benchmark for future mods.

I think 231 RWKW with a catback only is a bit high. My 6ltr WM Caprice when the engine was stock, dyno'd 204rwkw (pre-tune) with HSV headers + Cats and a Walkinshaw exhaust.

OTR and cam brought this up to 278.

Is it just me or are the VE's a piece of ****?

The VX LS1 5.7L in the VC dyno'd at 360 rwhp (269 kW). Custom headers, twin 2 1/2" straight through exhaust, no cam.

270rwkw from an unopened 5.7 is crazy. No other work done? No head work / otr etc?

 

[Not_An_Abba_Fan]

Nope....I just bolted it in and fabricated the headers by hand. It was out of a stock VX R8.

The other 10,000 vx r8 make no where near that with cai, tune and exhuast.
Maybe it was to do with the drive line you where running in your car or a happy dyno but there is no way a 5.7 vx r8 is making 270rwkw with just an exhaust.

 

[Not_An_Abba_Fan]

The dyno read out. The tuner did say he had never seen an LS1 go so high.

Drive line is 4L60E, standard converter with 3.08 diff.

Naaf it may be your custom exhaust, in which case you should definitely post that on the Corvette forum as by far the most powerful unopened LS1 / LS6 in world history. If it were me I'd cross reference the charted output with some other input like MAF g/s or actual intake CFM, fuel flow rate, injector duty cycle, load / cyl, because that's 60rkW and 60nM over the already HSV-tuned-to-buggeree VXR8.
See this for reference.
