Preliminary dyno numbers on the Beast

[NY65912]

Got some preliminary dyno numbers today.

The 3.8 Beast put down 360 HP at the wheels on the dyno. More tuning has to be done both on the dyno and on the road. I did'nt get the torque numbers.

Figuring 15% loss..........that's approximatley 414 HP at the flywheel.



We'll be doing an official dyno run next week.


We were shooting for 425hp

More to come.

Congrats!

Mike,

I'm thinking I'm going to need alot of left seat time in that car when we are at the track...

My own car is only 200 hp

[jcge]

Yikes !!! thats a lot of power

Put on a happy face guy... you've got a turbo motor with zero lag that revs to 8000+

[Jeff Alton]

I am gonna feel silly when I post the graphs of my 3.4.............

Cheers

Thanks fellas,

Bill still feels he can extract a little more power. He's upset that we did'nt go with higher compression.

Tim.......you know you can take her anytime around any track.

Now the problem is going to be putting the power down to the ground.

I've got a feva and the only cure for it is more rubber!

Tach goes out to be converted to 10,000 rpm.

wow, that's nice
very nice

Damn! I wouldn't have thought an air-cooled NA engine could pull that.

What are the engine specs?

[NY65912]

Specs are:

Based on a 3.2 case – boat tailed
3.2 74.4mm crank stroked to 76.4mm Re-nitrate
Using 2” rod journals utilizing NASCAR type rod bearings.
Center drill for better oiling to #2 and #5 rods (special center main bearing) engine will be able to turn to 8600 rpms, but we are holding it down to under 8000 rpms.

Custom Pauter Connecting Rods – using Raceware Hardware
Camgrinder -DC62 profile on a 108° lobe center
Race Springs, Ti Retainers

3.2 Heads – Dual Plugged & Ported

102mm LN Nickies 11.3 to 1 CR

JE Pistons coated

52mm ITB’s big injectors – FP Regulator (plus all kinds of other stuff)

Smart Racing Oil Filter Console

1¾” Nabel’s Headers into an (M&K Sport Muffler for street) M&K Shorties on the track

Spark and Fuel controlled by Haltech E-8 Engine Management System
Crank Fired Wasted Spark Accel Coil Packs

Light weight Al flywheel and HD clutch


Muahhhhhh

With that compression ratio, I take it this is a track only (i.e. race fuel only) car.

[304065]

Holy cow Mike. That car is going to HONK!

Have a great July 4th weekend, I can't wait to see (and hear) this car in person.

[rw229]

Yeah, I wonder what an engine like that would do with 9.5 or lower CR. Could it then go single plug and still be over 300?

I have wondered about the idea of a lower CR engine built to the same specs.

The displacement should provide the torque needed to move along nicely.

I'll use race gas 101 minimum.

Hey John, I can't wait for you to hear it in person as well.

Bill took it out on the road for some testing. He said that in the 2k-3k rpm range it was not a happy engine. BUT......over 4500 rpms he said it was like someone lit a rocket.

And, around 6300 rpms it came alive even more and pulled hard all the way up to the seemingly non existant redline.

As mentioned before, the tach is going to be reworked to a 10K unit.

I was most taken by the sound of this engine. Very hairy.

Wow!
