Batmowheel turbo upgrade?

Re: Batmowheel turbo upgrade?

may be why sticking LS engines in these shit boxes is getting so popular ...you could just stay on LS1 tech

Yeah try to get some correct answers on ls1tech I never saw a site with so many people with ego's but don't know crap about what they're talking about and give so much wrong and conflicting information. Plus heaven forbid if you mention somebody that's not a sponsor or say something bad about any of their sponsors.

Re: Batmowheel turbo upgrade?

I would rather see before and after runs at the track over dyno results. I know of a couple SyTy that were dialed in at the track and then brought to dyno. At the dyno it was further dialed in only to run slower at the track. Dyno's don't seem to load the engine similar to the real world.

In my opinion, it isn't the way the dyno loads the vehicle, it's the way most dyno tuners tune. Dyno tuners always seem to be looking for the maximum horsepower normally, toward the top end. When you tune at the strip, you are normally trying to get more horsepower and torque sooner allowing you to accelerate faster. That is the major reason why electric vehicles turn search great quarter mile times, they have full power and torque at almost 0 RPM's. This allows them to not need as much maximum horsepower.

Learn something new everyday. Always the dynos fault. Or the dyno "operators" fault or is incompetitent. Nice.
On a side note. If the batmobile design worked so well I believe PTE would have copied it already. They copy every other companies technology and design. Uh this was from a Garret engineer. Just saying.

Just need proof to justify the cost of this upgrade.

I don't own a batmowheel turbo, but I will give you my own :2cents: It use the stock exhaust housing, exhuast wheel and compressor housing, so it isn't going to be a miracle turbo. My assumptions and logic below is using the stock heads & cam and is probably best suited for a truck with mild mods.

-The stock turbo is efficient at making stock boost levels on the stock motor. If you're going to run stock boost levels, its probably going to make around the same hp. Maybe it is might be a little more efficient and lower the air intake temps.

-The stock turbo seems to start becoming hot air pump past 18psi. At 18psi, usually race gas, ally or E85 is needed. Small gains might be had with a more efficient turbo at the 18 boost level.

-On a stock motor, if the turbo is efficiently providing more air, it makes about 10hp for each additional psi of boost. If the batmowheel turbo could supply 22psi air efficiently, it make about 40 more hp than the stock turbo would make at 18psi (assuming the timing is the same).

From what I have read it sounds like from owners with this turbo, that they report it has quicker spool up. I read on facebook someone ran this turbo a(or maybe it was a waller or 20G) at the track on stock boost and it ran stockfish times, which doesn't surprise me.
