Boosted engines are not always on boost.

There is a correlation between a tight quench and the quenching effect (as opposed to squish) that aids in heat transfer, a tighter quench aids turbulence off boost (squish), and anything that allows less timing for the same power production can be considered a good thing, all else being equal.

What's wrong with a solid roller on the street?
IMO, any 'performance' engine build DESERVES a solid lifter arrangement.. but that's just me.

Pass on the supercharger /not a good move with the current status quo.
You say you got 10.5:1 , bit much? No , WAY much to 'shove/force'. Injection/boost.
(93 in Texas , e-85 if need be .). You must make sure that your fuel system is compatible with alcohol fuels to use this benefit ! ) What type of vehicle is this? Road car , ? Strip ? Drag car .?
Improvements -: solid lifter valve train. hydraulic for heroines , mechanical for men!
What is a 950 aed? ( pardon my ignorance, is that a carburettor?) , if so, mmm, bit big ??
Drop from super victor, to victor junior , should suffice , IMO.
'Shorties' headers?? ... That's a bummer!!!!
560 hyd roller, got more specs on that? Like a part number.?
Let's know.

Switch to e85 and run the pro charger at about 10-15psi. This really isn't rocket science. Fuel makes a huge difference and most of these posts don't take that into account. I'd leave the rest as is fr now just have your carb tuned for e85. You may need a better fuel pump too.

Oh and be prepared to watch the gas needle drop fast. E85 runs more volume than gas especially when under boost.

pressure check

Hi All

When checking boost pressure.The type of exhaust system you use will have some effect on boost psi.And compresson will also add heat.

I ran the car on Saturday
.8362 reaction
1.99 60ft
11.96 1/4 mile @ 120.94 mph
This was all test and tune not running the car very hard, I do need to swap to a real slick instead of the drag radials I have. Going to go with a taller tire as well I have 275/50s on it now. I would like to go solid roller and swap to a super victor 2? What do you guys think?

The MPH indicates very low 11s.I think its time to tune the suspension,the engine is making decent power.
If its a serious drag car,then the gearing will need attention when you get better hook.

I ran 11.9s at 110 mph with one car and 114 with another car,your 121 mph is good for low 11s,maybe high 10s

That sounds good to hear, I know the car has more in it. I need to run a taller tire, I'm crossing the finish line at almost 7k rpm. The car has 4.11s now, and I only launched it at 25k rpm. The car has tube a arms and k member with a pinto rack. I weighed it at a truck stop and got 2900 pounds, the rear suspension has all tubular components as well with comp drag shocks. What do you think?
