Bring it out to CA so you can run on some tracks with me  |
Would love to come out, it's only 20 hours or so drive!
How about you bring your car to Kansas
The 300whp is just a guess... I'll add power until the charge temps start climbing out of control... The 4 lobe twin vortecies simply move air so much cooler/efficiently than the M62, that I'm hoping I can keep charge temps below 200F at even 12-14psi in 70 degree environment and fullly heat soaked (or atleast as much as I can get without being ont he track). If I can't hit 300 w/o an IC, then I can't- no big deal. The car is quite quick
and very responsive as it sits with only 10psi boost...
The M62 would certainly have been in the 300*F charge temp arena at that 12-14 psi pressure (using my equipment), as it was pushing 240+ at just 10psi with ~70 degree temps. The TVS is only pushing 175 at 70 degree temps and it has less drag (drag: as advertised by the manufacturer, I have no way to substantiate this...)... Again, both in fully heat-soaked states. I'm only looking for a delta T here, as everyone's sensors seems to give different readings....
Thank goodness for a climate controlled dyno room. Winter is coming into the midwest! I'm relentless on the rollers. I drive the car hard before I get to the dyno and then do several pulls back to back without shutting the car down. I tune with the car idling every two pulls typically. Then pull a couple times and tune again. The guys at the dyno said I've got the second most pulls of all their customers, just short of the owner... That's hillarious... I think I'll get him knocked off his horse by next weekend
Back on topic, fortunately, I've got sensors all over the car and data logging ability, so I'll be able to see these temps very accurately as I strive for a track safe 300whp on a non-ICed TVS... I've got my glass half full, as I think it's doable without pushing it too hard
Best,
Phil
