Ok so I finally got it dyno'd on saturday morning on a Dynapack. The car made less power than I had hoped for, but I guess it wasn't bad for the condition of my engine.

My engine (original engine with 59k miles and stock ports) is running very low on compression (60psi front rotor and 68psi rear rotor) along with a most likely blown coolant seal (tons of white smoke at end of dyno run when let off the gas). You don't have to tell me. It will be rebuilt in the next coupler months and large street ported.

The car made 349 rwhp at 14 psi. I would have run it at 15.5 psi also, but after seeing my AFR I opted not to. The AFR peaked at 12.8:1. The reason being, the car was tuned with an unknown leak in an intercooler coupler and I fixed the leak, so it would need to be retuned, but i didn't realize the leak was as bad as it was.

Torque was absolutely horrible at only 253 lb-ft. Not happy but probably due to the low compression also.

I Will post picture of dyno graph in a few min when I get it scanned.

 

Here are the graphs....the first is HP and TQ, the second is TQ and AFR. Pay most attention to the red curve on the graphs. The other curve was warm up run.

 

That is pretty nice numbers, especially considering the motor condition! I would be totally happy with less than that much horsepower on my setup at 14psi( hoping for that much) . But I'm sure a expert on here will tell you how well your doing. Good work man!

 

which T04R are you using? the HKS one?

I dyno'd at 438RWHP @ 1bar

 

No it is a kit I put together that was a "replica" of the HKS kit. Turbo is a Garrett TO4R with .84 A/R. All my mods are in my sig.

 

When you rebuild the engine are you going to port it? If so, what kind of ports are you planning on using?? That should help you out quite a bit!

Just seemed strange that you dyno'd at 100RWHP less than me???

 

He stated he had only 60psi on front rotor and 68 psi on rear rotor for his compression numbers. Those numbers don't seem that bad for the condition of his engine...

 

I will be street porting it using a template from Mazdatrix. It should be making plenty more power than it does now because of the port, but mostly because of the good compression and tuning for about 16 psi.

I think the numbers aren't bad for the condition of the engine. I mean 60 psi compared to the ~130psi or so of a new motor.

M-P

 

yeah i just read that now sorry i skimmed beforehand.

 

I too was a little dissapointed with the numbers my SR stage II put out. I have'nt checked my compression, but the motor has 49k miles on it. What was realy cool though, on Ralph Friends (Groundzeromotorsports.) mustang dyno my car at 14psi I made 340rwhp and 289ftbls. Then at 16psi I made 392rwhp and 330ft lbs! I've never heard of 25ish rwhp per 1lb of boost. I would'nt beleive it myself if it was'nt my car. I have a sheet showing the boost vs a/f ratio if someone does'nt beleive me. But anyways, I too plan on a street port. I'll probably be talking to Rob@Pineapple about something that will help spool but still be able to pass emmissions. CJ

 

stock ports right?

 

Yeah stock ports. CJ

 

Those are very good figures bearing in mind the condition of your lump, i would be chuffed with these figures with an engine thats about to fall apart.

You could have reached higher on other rollers that show more than you really have.

Should be impressive once you've rebuilt.
