Just got my vr4 dynoed?

just had my vr4 dynoed on a stock engine, head, turbo, 255lph fuel pump, fmic, 3" exhaust, kn filter, boost controller, Keydiver stage 3 ecu. put down 187hp 194tq at 14-15psi with 13.1 AFR. Good, Bad, or Normal? sounds normal to me, just wondering what you guys think?

13:1 afr, I hope youare joking?

Are you serious? 13:1 AFR? /ubbthreads/images/graemlins/banghead.gif

 

Yes, seriously actually the afr was 13.3 after looking at the printout. whats your guys opinion?

 

[4thStroke]

You need to richen it up, a lot. It depends on whos tuning and what their preferred AFR is, but 11- 11.5:1 is a good range.

Ever seen a plasma cutter in action? Run that afr any longer and you will get a sweet little piece of slag that used to be your piston.
Hey at least it makes as much hp as a mustang /ubbthreads/images/graemlins/smile.gif

Uhhh, that's going to make things worse.

Honestly, depending on the dyno used, I'd expect a little over 200whp with those mods.

haha, im trying. i think ill throw about 10 more psi at it



You serious? We recommend RICHENING the AFR and you say you'll just throw more boost at it? GFTO troll. /ubbthreads/images/graemlins/uhh.gif

 

Our cars came stock with more hp and torque than that. /ubbthreads/images/graemlins/dunno.gif

 

What injectors are you running, stock?

My Dyno sheet may give you a baseline as 183 has no modifications less the BCS restrictor removed. Full weight with 88K on the clock. I pulled:

174 (WHP)
191 (Ft lb)
14.4 (AFR)
13.5 (Boost)

*The Dyno operator was an idiot so ignore the "MIN" and "AVG."

Stock rated HP was 195 bHP (brake horsepower, or power at the crank.) He's reporting wheel horsepower, which takes into account drivetrain losses. A stock car probably only put 150 HP or so to the wheels.

ease up fellas... newb, it shouldn't be that out of whack with a matching ecu chip. Do you know 100% that this chip matches the mods, did you change something after getting it?

Edit

I looked at the dyno sheet more carefully. 14.5 is your leanest value. The value under heavy boost was 11.5 which is still a touch on the lean side for a stock GVR-4 but probably nothing to be worried about.

 

I'm Ron Burgundy?

 

No i didn`t change anything it was tuned for 450cc injectors-stock, gvr4 maf, How could i richen it up? FPR? Clogged fuel filter? Recheck timing? My dsm has been sitting for about 2 years since its been running. Everything is stock with bolt on and no i was just joking, i`m not goin to throw any more boost. when we were adjusting the boost controller it would jump to 20 psi and i`d back off of it but it was making over 200tq on those runs. It was a awd dyno too. thanks everyone

On a mustang dyno that is not to bad with the little mods you have.

Rewire the fuel pump. That should help.
