Hello fellow boostaholics... Sorry about how long it has taken for me to post some updates on here! I have done some major changes to the combo this past winter and gave it a try yesterday (hold on)... I swapped the cam, intake, hat, rockers, gears and some minor parts over the winter.. All of them I thought were boost friendly and still think LOL.
I changed the victor intake out for a tomahawk intake & matched it perfectly for my heads (the out of the box victor had way to big of a port for the heads I'm running and the tomahawk sits also much lower). Here's the specs for the old cam that came with the motor when I bought it Specs: 280/292@.050 & .726/.693 lift 114 L.S.
The new cam that I ordered through Butler performane is also a solid roller but much much more realistic it's a 242/236@.050 & .570/564 with 114lsa and I installed it at 110 ic. That's with a set of 1.5° ratio rockers (the old 1.65° T&D setup was to messed up by someone to be used again).
I also recently changed my 3.73/spool for a set of 3.08/posi and man what a difference! Also put a very famous Robert1320 non divided EV hat on it with a custom 2" spacer.
I have street tested all of the parts above and it's much more responsive and does act much nicer I also love the cruise rpm's of the 3.08 gears.
So first passes with the new combo.. I put it on 116oct gas to be safe on air/fuel etc. but pretty much had the street setting on. Went with M/T street radials 325/50/15 and had massive traction issues all day! Our track is all asphalt and only minor track prep is done but anyways!
First pass I went down the track pretty much spinning all 1/8 of the track and put down 11.50/135 with 2.1 60 ft. Yikes!!
2nd pass I spun the tires a bit less and went 10.99/137.
On my 3rd pass I got 1.8 60 ft. with 10.50 @ 138mph and on my last pass when I finally rpm'd the motor to 6400 each shift I got similar 60 ft. btw. but better speed through 1/8 with 110 (to a 107-108 in the earlier passes) but had to let of the gas before the 1320 mark because I blew a waterhose but coasted through the traps with 10.40/130 (that felt actually like a 142mph pass).
So... I'm pretty happy with the first outcome, I know our asphalt track likes bias ply slicks much more (for some reason) and I'd like to put my car on real soft slicks before next time and 60 in the 1.5-1.6 range not 1.8
The air fuel was about 11.5-11.8 down the track but I felt like it wanted bit more. I'd like to richen it up a bit on the topend for next time. Bost was around 15psi (the lowest I can go... damn wastegate and 3.08 gears don't mix well). Also the car might loose some weigth.. right now it's around 3650 with me in it.
But hey I got to beat a pumpgas 565 bbc Trans-Am with my traditional Poncho
