Driving Ambition's latest 3.5L SC project (535 rwhp)

[DrivingAmbition]

Here is a dyno sheet from one our most recent customer car projects.
91 NSX, 3.5 liter Comptech stroker, 2.1 liter Lysholm SC (very similar to the new SOS blower), Driving Ambition Aftercooler, and CT Eng. manifolds. At 11 psi we are right at the SC max rpm and the customer wants 15 psi. So we are going to a larger SC, the 2.6 liter Kennie Bell. I will try to post some sheets in the next couple weeks when we get it back on the dyno. Cheers, Shad

that sound really good. right now i had a SOS supercharger on my na2, and thinking about taking it out and go for lovefab turbo. but don't like the lag of the turbo. so if i stroker the engine to 3.5 with the SOS supercharger i will make 535rwhp. i think this will be a better way to go. can you give me information about the troker kit.
thanks

Build spec please! :biggrin:

Very nice numbers. Are you running stock cams?

 

[NSXLuvr]

More details please - HOLY SHIT!

 

[NSXGeek!]

Excellent numbers. Based on them, I assume this is race gas (100+ octane?) On regular 91, you'd be looking around 10-15% lower - just so that we have our comparisons accurate.

Holy Christ!! This is some insane power!

I assume that the hp is rwhp as you say, but why does the graph say "fly wheel power"?

I would love to see a vid and hear the audio of a Kenne Bell on an NSX at WOT. :biggrin:

Two Questions:

1. What would be the 0-60mph of this vehicle now?

2. What would be the top speed?

Two Questions:

1. What would be the 0-60mph of this vehicle now?

2. What would be the top speed?

Depend on a.) wheight & b.)drag.

With a < 2800 lb car, good tires and a good driver, I suspect it will be in the range of 3.3-> 3.7.

Top speed should be in excess of 200 MPH with a modest spoiler (not sure if a big-ass wing would still hit it though)

Keep in mind the p/w is near that of a McLaren F1

what will it be on 1/4 miles with this powers.
thanks

Has anyone confirmed whether the chart's fly wheel horsepower is actually rear wheel horsepower?

I believe the 0-60mph would be in the mid-3's

Would the top speed really be over 200mph? Wouldn't gearing be an issue?

Also what is the cost of this conversion and how does it compare to other high horsepower set-up's like LoveFab?

Has this project/thread died?
