From BTR...
Ok guys, sorry for the delay in testing this thing, but I finally got around to doing some more single plane testing yesterday.
The results were as follows...
100% stock GM crate 6.2 LS3
235-25x custom cam
1-7/8 dyno header
All pulls were run with EDDY elbow w 102 mm TBI
Eddy SuperVic 594hp @ 6800 490lb-ft @ 5900
Holley Split race 603 @ 6800 494 lb-ft @ 5900
TFS single ( this was ran with a very nice custom 1000cfm carb as there are no injector holes) 580 @ 6500 rpm
These test numbers are the average of 3 pulls all made to 7200 rpm .
All pretty close IMO and probably wouldn't see any difference on the track between the top 2 manifolds.
A 1 inch open spacer HURT power to the tune of 8-10 hp on the EFI setups !
Was worth a few on the carb setup .
They both had pretty much the same distribution as well.( 8 wide band O'2s and EGT'S.
