F1X cam I did
Too early of an ivc point.
Stevie Fast was asked about the motor in his ODR car once... his reply was that it was the biggest and baddest nitrous motor he could build.... then he stuck a blower on it....
Things that make you go hmmmmmmmmmm......

these are the numbers
IVO 42 IVC 82
EVO 94 EVC 38
80 degrees of overlap
Not really too much of a build thread-just a simple 402-I
guess you could say it was one of my cookie cutter builds-lol!

Martin-delete this is if you want buddy-I don't want to take away from your thread.
But when guys like ATVracer and LilJohn start posting my ears are wide open.
BTW-from the trends I'm seeing my next cam is real close to your Stage 2 blower-been working on a cam that doesn't make my cloths smell like fuel-but still makes jam.
I have some dyno results I can share with you via email or pm.

LilJohn pretty much took me under his wing along with Tooley a while back. They've always been my biggest contributors when I need someone to bounce ideas off of. Wayne also has taught me a lot about plug reading and what to look for and what to do when those situations are encountered.
I actually wish now that I had gave the Stage two cam a little more exhaust duration to kick the EVO event out earlier. These centrifugal blowers are so peaky by nature that they need help in the EVO department to bring up the torque numbers after peak torque helping to broaden the torque curve as Tooley spoke about with his 454. IMO they also don't need too late of an IVC as they continue to make power with RPM as long as you don't run out of blower CFM in doing so by spinning them harder. This is at least what I have seen in the 10-12 blower cams I've done in the past couple months.
I'm doing a 468 BBC F2 blower cam right now and it will follow the same principals I've learned from my previous blower cams.

Tooley has been around the game a long time, and he's been around the 5.0L Mustang era where I learned alot and pass it forward on the LS platform. People make it sound like the wheel was just reinvented but it wasn't.
I will email you a graph of 3 different cams, 2 of the graphs are from a Novi 2000 and the other is the F1R-at first you'll think the bigger cam obviously should make more power-then consider the F1R versus the Novi 2000-then things are not so clear again.
The Novi 2000-doesn't nearly have the airflow of the F1R.
This is why I like the Stage 2-and since those are just .050 thou numbers-the advertised can be quite a bit different.
It's always nice to bounce ideas off people.

Stage 2 Blower Cam is:
286/296@.020
234/240@.050
151/157@.200
Add overlap to it and it picks up power when there was little overlap to begin with.
And dont try to blow down 1000 hp engine with 240 degrees of exhaust timing.
Was the original cam spec'd for that combo? I cant see anyone in their right mind doing so. Looks like its closer to right now! Screw changing pistons, why wouldnt you just pulley it up

With a centrifugal there comes a point where spinning the blower harder reaches a point of diminishing returns sort of like with a turbo. Only it takes more engine power to do this where as a turbo doesn't. When you reach that point you'll actually lose power from trying to turn it that much faster while not really gaining much anything from it other than added heat in the intake tract.
While I agree the blower could be spun harder than it is being spun now, the motor having the compression it does on E85 with an air to water intercooler is just begging for more cylinder pressure. Not only that, but it takes a powerful N/A motor to spin a larger blower like the F1X and more compression will only make that job easier.
If this was a race car with a gear drive I'd spin it well past its "rated" maximum rpm as the guys in X275 are doing, but since it's a street car I'd rather not and find power in other areas.
I wouldnt build a F1X with a belt no way no how try to drive that geartrain, but yeah if you know you can only run xx,xxx rpm with a belt setup reliably, then make more power NA is your only route. But a air to water setup with a belt?

You've been around long enough to know how to make big power, so I don't need to tell you twice.
