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!!;)

15 psi on R I P 2.8

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'.

Fair enough.

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. :noidea:

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. :happy0180:

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