I hear ya, the numbers haven't seemed to be a problem, getting the numbers to match at the track is what I keep hearing the issue is. I hope ya get it to track well then I won't be so hesitant to do a 416.

What boost and pulley size are you running? I see OD rears

I made 680 through the auto at 16 psi, blower only on the 376. It was good for a 9.98 at 138 mph. Any more boost it would make more peak power but it was slower at the track because of belt slip.

I should have it up and running by the end of this month, just in time for the cooler weather.

And I would think you could use the same pulley set up on a 416 and make about 13psi and 700-715 rwhp.

And you would run 10.50's at the track. Good luck with that. At least you'll save money bc you'll only need a 6 pt bar!!

I have a 6pt bar and don't want to have to get 8pt, until I decide I don't want to drive the car a lot any more. So a 10.0-10.7 is what I want until I decide to stop driving the car and start trailering it. In cooler weather I should be 10.8-10.9 now. I ran 11.1 last week and it was 85* out and still have room to better the 60'.

So the bottom graph on page 1 is about right, it says 16-17psi for a 2.8 OD rear and I am sure you have a decent cam so that would drop it down to 15psi. You should be fine then, I would have thought you would have made alittle more than 700 but it is just a number it only matters what you do at the track.

Boost is a measure of restriction. I run mast black label heads. They have decent flow numbers,Lol. I think I have another 30 or so HP laying around on this setup with a proper tune. Track numbers tell the ultimate tale.

I don't know how relevant it is, but I will throw it out there, because I am bored.

I have not been able to find efficiency charts like that for the eforce, but it is a 2300 TVS rotor assembly so it cant be far off in numbers.

My LS402 makes 724 hp @ 12 lbs. Compression is 9.9 to 1. There is more in it but the tune is not super aggressive.

Hope that helps.

Yeah but you can't offer track numbers because your car weighs 700# less.
