First of all, your results don't count. I'm not counting VMP's 9.9 at 138 on 8-9psi (82mm) either. Second, is Kumar's tune really the same as all your other customers? He has a Fore return style fuel system, not the same for the rest of your customers, some are not even required to run a bap, right? He also has every possible supporting mod that $ can buy, which improves his et. Give me someone else...
Define "ceiling." I agree the whipple has more potential, not necessarily on pump gas, but it's a bigger blower and with boost that requires race gas or e85 it'll outperform the TVS, but not sure how much more. We all know a TVS will easily go 9's, and 8's, so either one is sufficient for insane results.
For the most part, the compressor. It's a pretty good size difference. By no means a slight at the VMP. That VMP flat out performs. Race gas, e85, very aggressive tune...these are all options you can do on any SC. But however you get there, I still believe the Whipple has the higher ceiling. I am not personally looking for the ceiling. I like the slightly mild, and safe, tune that I get out of the box with Whipple. If I was looking for an insane high ceiling, I would have gone with the 3.2KB. That thing is just a flat out beast.
Dynoes are subjective because there are a ton of variables that come into play. For one, all dynoes are different. Then you have sea level, humidity, temps, tires and more. Dynoes should be used more as a tuning tool than seeing if one setup makes more power than someone elses of the other side of the country. The only true measure of power is trap speeds.
So you don't need a bap to run up to a 3.25" pulley? that's more information I was completely unaware of. Roundabout how much boost is that?
Im assuming because of the variance in dyno numbers based on different dynos and all the correction and loading factors. Theres can easily be a 70-100hp swing on a dyno dynamics vs dynojet when youre approaching quad digit power.
sounds like trap speeds has the same problem as the dyno. Not easy to make an apples to apples comparison. Burnin4 is trying to compare his VMP / Auto to Whipple / PP manual cars.
Lol, I personally didn't even dyno my cat prior to putting a SC on it because the dynoes would have been on different days. In the past, I dynoed one of my cars multiple times on different days. There was no change in setup and even on the same dyno. There was a 20whp difference and the only change was different day lol.
So you are officially saying that your customers running your tune can swap to a return style system with zero changes to your tune? Yes? And, you are officially stating that a bap is not needed at all on your tune with a 3.75/3.625 pulley? Just making sure everyone knows your exact advice.
you guys tuned that car on 15psi, right? I'm not comparing my auto setup to a manual whipple setup, I'm simply looking for ANY whipple results, on a whipple tune running the 3.625/3.75 pulley and comparing them to my results, which were derived from multiple drag strips under different conditions.
