Only 3 slots available. HP Motorsports in Katy wants 2 of them but it is first come first serve as I told Jay and he hasn't paid me yet. So get in now (only 3 at this price) or wait for the price to go up!
Finally got a overlay dyno chart out of my customer Roho Snyper (his facebook name)
Blue line is the holley hi ram on his procharger f1x blower and race air to air intercooler
They approached me to build them a custom air water because they were seeing 200F at the end of the quarter mile.
With my intake they stay at ambient with water only (1.5 gallon total water system), with killer chiller on 15 below ambient.
Tune is nitrous tune but running boost only so rich and no timing in it.
going to tack up another ls7 vette tomorrow the the batch 100% welded and shipped to parties.
Getting caught up now that we have flanges and fixturing g2g
For all ltx based stuff soon I will be able to do testing at whim just about any day as my personal lt1 2016 ss camaro is finally coming back to life (going to tuner in morning, looking for 700/700 on 93 oct low boost 5-7psi, big turbo cam and 416 with twin 6766 turbonetics)
