Torque is cheep.
Now if they only made some monster CVT that is race-able.
"How many gears does your car have?"
"All of them."
Did I say I really liked seeing all those gallons of fuel atomize and get swirl sucked into the intake valves.
Tho putting some fine mesh on top of the trumpets would make it much less scary to watch. All it takes is one errant piece of something falling out of someone's pocket to end the day.
Wonder how long those old race motors lasted with just a fine screen mesh over the intake trumpets.

One....
Agreed about the mesh. Actually, I was also somewhat suurprised that they shut it off from redline, rather thhan let it run down to idle & then shut it off.
Abby, come on, lighten up.

Without doing so, the plug reading was always questionable, especially on water cooled engines.

Is torque cheap? Thats bigger displacement usually, while hp is cams, intake, and heads, so I guess you are right.
"all of them". ..............funny. Actually, for VR's info, we have similar gear spacing to the NSX turbo. On the race track, its a 3 speed.
. As far as the mesh goes, yep, that is scary. you should see how much "stuff" I dump out of my kn air filter after each session. sometimes , its a pile of sand like at laguna!
That engine is a thing of beauty. Funny that with a restrictor, it goes down to 440hp and 400 torque for classed racing.
A bit OT, but in karting, especially with aircooled engines, the driver was asked to always do a "hot cut" (cutting the engine off at WOT on the longest straight and then coast into the pits...of course raising their right hand to let other drivers behind them know) in order to let the tuner get a good plug reading on entry to the hot pits.
Without doing so, the plug reading was always questionable, especially on water cooled engines.

CVT can have ANY gearing that the controller specifies.
Can be geared to do whatever you want.
Just because the current crop of CVT's are used to maximize efficiency/fuel use doesn't mean that's all it can do. Ain't it.
Sorry for the OT.
So anyone got any vid of the beast storming around Road Atlanta?

This is true, but if it was used for optimum acceleration at any speed, it would run the engine up to max hp and stay there. sorry for the continue of OT.
Now, found a day that works for the race yet??

And, if you had been paying attention, yes, I have already suggested a specific date, and you responded. Now all we need to do is fund the track rental. Again, you already know this, since you responded to this in the other now-closed thread.

Wish Mike was still posting here, but it's threads like this that finally ran him off. Our loss. However he's still active on Pelican and you can see the build info on the engine here. FYI he's a talented machinist who did his own ITB setup, sleeves, studs and much much more. The car is a work of art that goes waaaay beyond the engine, with a completely custom suspension setup (and I'm NOT talking about just shocks and springs), transmission mount setup and more. The brakes are gigantic Alcons behind CCW wheels. All this from a busted, abandoned 79 he found down the street from his shop and decided he needed a project.

Yeah, I was just getting my last one in just before I agreed with Bob. 
OK? done!
Now, I have been paying attention with the race weekend proposal. Are you going to start a new thread? If you do it, Ill keep it all business if you do.

I do not believe I have made any cheap shots subsequent to the PM that you & I received from Bob Rouleau. You, on the other hand...

We find it's much safer / easier to do this on a dyno

Necessary on engines with carbs, nothing to do with water vs air cooling
