Well, surprised at my numbers is an understatement

I was the last one to go, only me and the tumbelweeds...not on purpose...Tech had a little mishap while putting the leads on to read rpm. Any way's one new rear diverter later. And waiting for a old 27 open bucket with a small block that was in need of some some tuning.

335XI "JB3 8D3 MAP6" (dynoed in Mexico)....everything else 100% stock, including air intake.

STD corrected
355 HP
382 TQ

SAE corrected
346 HP
372 TQ

Very happy with the results for only ONE mod on Map6 and all wheels a spinning.....Thanks "Terry."

Post the graph?

Here's the graph...The boost is off by 2 1/2 lbs....

Did you dyno the car while stock?

[Jimbob65]

Nope,
They did have another XI on their list that did 245 SAE. 250ish STD corrected. Although this is nothing compared to my drag car dyno's, I thought my car did well for a JB3 equipped XI. I wonder what a open air filter/filters would do?

Oh yeah, there was a turboed M3 making 602 SAE today...Very impressive...

Why do you say that the boost was off by 2 1/2 lbs?

Great numbers!

I think he is referring to AWD which typically has more driveline loss than RWD.

Great numbers!

Their meter reads to 100PSI. They told me that it reads off by 2-2 1/2 PSI down in the lower scale of the testing device. I have known the company for years, tons of FI cars go through there. They would have a huge number a vehicles with Boost gages to verify against.

They did have a SRT 8 charger with a Novi 2000 supercharger (can't remember if that was Paxton or Vortec). Anyway, it put down 529 SAE rwhp. One of the BMW's put down 602 SAE rwhp. A new STOCK M3 put down 331 SAE rwhp. It was a pretty good day for dynoing...

Grats Jim on your run.. I had to leave to go back home but that seems close to my numbers with the same mods you had. I dyno'd at 353awhp with just the JB3 and some race gas, so we're very close.

Now come out to PacificRaceways and lets see you put that power down!

re read what hotrod said,He ment theres more driveline loss with 4 wheels spinning on a dyno.

Not breaking the tires loose

Thanks

It's good to know I'm right in line with the power your made on Map 6.

Did you dyno at the same place for your 353? I could campare boost levels to yours! I searched on here for any old post with your old dyno...but no luck.

Anyway, Terry was thinking I might see another 10 more with Air filter/filters....I might have to try that out after all.

Nice! I like seeing all the modded XI's on here

Here's for your bud.....
Here's for supposed 20 PSI on stock Turbos...and the 11.7 he rode in on!
