Went back to the dyno this past Saturday. It was a lot hotter out than last time when the car did 523whp on pump+meth. With the same conditions as on the pump/meth runs it could've maybe done a touch better, maybe 540 even, maybe not. It shows just how close meth/pump numbers can be to a more expensive race gas+meth alternative when you're already maxed on the turbo side of things. However, with race gas some additional timing managed to be had without knock through the top end helping power not drop off as quickly in the 6-7k rpm range.
These are the one-off set of stock frame upgraded turbos from Vargas around which so much heated and imho unnecessary debate happened last week. These will never see production. These are not Stage 2 Batch 2 turbos customers will ever see. These have a one off housing that was used to just put these together in the name of "science" to see the effects of a lot more machining work on the turbine housing in terms of hp while preserving the exhaust manifold in place.
I personally take it as another fun day at the dyno, great numbers out of the backup motor I've put in that I picked up for a bargain and didn't get screwed on :) That is exactly what the previous post was also about from my end of it and I hope this one won't turn into what we had in the previous one again.
Log attached to prevent any bloodshed LOL I think this is some kind of a stock frames turbo stock motor record, with a tune done in the most appropriate of ways possible (i.e. not testing hardware limits with bottom end boost or torque), even though its a hybrid of VTT/ASR hardware. The rpm/mph chart below the power/torque graphs is to show the RPM pickup cutting out :( dyno shop will need to sort that one out hopefully soon
GREEN line is pump/meth
RED/BLUE lines are race gas/meth
Both tunes run the same boost and wg duty cycles. Only thing remaining is to try maybe using an E85 blend with meth, possibly.
Cheers
