Hey cjb80 what you think about octan boost by nos ,
the one you add to your fuel. does it give you higher
octan gas?

 

CJB,

You mentioned you had new pistons. Are they just forged, or do they drop the compression as well?

Is 19 degrees significantly retarded from a naturally aspirated version? I'm not sure what stock is...

Thanks.

 

I think the pistons he has drop the compression.

 

damn is all I can say....

Those are some impressive numbers (I know you are guesstimating but still). I bet the car is scary as ____ now...
so you are pretty much done with the motor? no more power, huh? I'll give you a year then you'll be craving for more...

So yellow S2000s MUST be the fastest, huh?

 

Echo...

 

Holy cow, I can't believe how many people are interested in if I have a bored throttle body. Yeah, I had mine bored out a long time ago, but I seriously doubt it affects performance at all. When air is pressurized it will push it through anyways. I had it ported by Pro Flow.

The pistons are forged 9:1 pistons. I believe stock ignition is around 40 degrees at 9000 rpm, 19 degrees is pretty conservative but keep in mind it's also tons of boost.

I don't know if he'd appreciate me saying this, but based on Mike's experience advancing timing just a few degrees at high boost levels yields HUGE gains in power. Perhaps 30-40 hp. But then you get closer and closer to the edge of detonation. (Where peak power is made)

If I were to run it up to 25psi or more, I would probably back ignition down to 15 degrees or so.

Chris,
At this point better safe than sorry. You have nothing to prove. Nice job with everything. You have the patience of a saint. I don't on the othe hand which is why I'm so glad you've done all of this to pave the way for me...

CONGRATS,

Please, please take this monster to the track and do some off idle launchesand post the time slips!

Hi Chris,

You've been on point for the rest of us for months now. Glad you made it to the end of the tour. Enjoy your beast.

And congratulations: on power-to-weight ratio (roughly 400 engine HP per ton at 19-20 psi of boost, according to your seat-of-the-pants dyno), you've pretty much surpassed everything out there, including a Ruf R Turbo (345Bhp/ton) and a Lambo Diablo (392Bhp/ton), and you're closing in on a Ferrari F50 (424Bhp/ton).

I can't even imagine how it must pull...
