The dyno results are in and...

Not bad for a hot August day!

539 rwhp and 528 torque on a Dynometer! I'm very happy right now! Just have to see what she'll do at the track in cooler weather.

That's pretty good. What's your compression?

The pistons are 9.6:1

 

[Sactown]

congrats! Nice numbers!

Tq numbers look good must be fun to drive

It is! Fun to cruise around town and a blast in a straight line!

I'm already wondering how to squeeze more out of her! LOL

 

[MassMustang]

So... I always have "what's next" rolling around in my head. What's the next mod to reach 600whp?

I'm happy with my 127350's as they're easy to manage around town or in traffic. I'm running the 6-rib 3.12" pulley in a blow-thru setup and the HPX-E MAF sensor.

Ideas?

 

[TheKurgan]

Easy, just pulley on down. That 2200 will love it.

400+ torque under 3000 rpm, and over 500 by 4000 sounds like a really fun car to drive around town. Congrats!

Oh, it's fun to drive and can really pull without dropping to a lower gear first! I'm just thinking "what's next?"

Maybe a smaller pulley and 8-rib conversion and bump the rev limiter to 7K.

You'll definitely want an 8 rib swap if you go to a smaller pulley. The nice thing is as you spin a centri harder they make better torque.

8 rib, down pulley and do a waste gate setup.

Maybe not. I'm running a 6 rib with a 2.66 pulley. I just use a ThumpRRR tensioner. No belt slip at all.

What are you running for tires? With that much torque and 4.56s I imagine it's like driving on ice.

Would you need a tune revision? Or will there be enough wiggle room for the extra 60hp worth of boost?

I run 305/45/18 NT555R's which are 28.75" tall and reduces the effective gear ratio down to 4.30:1. I haven't hard launched the car yet while I work on a few things, but I'm sure a "running burnout" would be easy. I typically end up working the pedals though to get it moving without "drawing a lot of attention".

Go 8rib with and overdrive crank. I'm making mid 700s with a 2200 on E85. 302ci, same cams you have.

 

[TheKurgan]

I would get a revision. That's pushing alot more air.

 

[MassMustang]

I would agree that if I pulley down a couple sizes, I'd wanna:

1) upgrade to the 8-rib with an overdrive pulley & new tensioner
2) get an updated dyno tune.
