    1/4 mile discussion and time slips post here!

    Twins with Twins, Anyone?

    Damn Ken, I don't think I want a Dmax boat now! Coolest project ever but the same issues we had when Tony B. built the airboat, none of the stuff would hold up to it like they did with the gas engines, too much thumping from the diesel!

    #113 on the list -The A Team(Clay) went to the track today with his Stock motor LBZ and got a new personal best of [email protected]! They asked him to leave afterwards so he's pretty happy with that! Nothing has changed other than a better air day for him and getting his 60ft down pat which...

    Intake(Y Bridge) Air Temp

    A good average we see is 1psi drop per 100* drop in temp on an intercooler. A super efficient cooler will get you .5psi drop per 100* drop. The higher cfm flowing cores will not drop the pressure across them as bad but can also not cool the air as well for the same reason. Before my banks...
