Got this from David at Bullseye Power. stock B16A engine with springs and retainers. 17psi on 93 octane. 62mm turbo.

Blue line-Cast 7 blade wheel-378whp
Red line-Billet 6 blade wheel-383whp, a 5whp increase in peak over cast but look at over all curve
Green line-BatMoWheel 6 blade wheel-440whp, a 62whp increase over cast!!!.

Just a wheel upgrade for 57 more horsepower than a billet wheel. and look at all the available power under the curve. thats on only 17psi. not even pushing the 62mm turbo. imagine the increase in power and area under the curve at 25+psi

Bullseye just released these new wheels which are proving to be a HUGE upgrade for even billet/ballbearing compressor wheels and housings. with numbers improving through out the entire rpm range and building boost faster.



regular Billet 6 blade wheel from Bullseye Power


new BatMoWheel from Bullseye Power


please note. these are not the same size wheels though. the billet 6blade is actually a picture from my build and the batmowheel is for a holset hx40

 

damn turbochargers are improving quick. imagine that compressor wheel with a gamma-ti turbine wheel from borg warner!

 

good info bump.

 

I never believe these scenarios because it's easy fudge these numbers with tuning alone let alone boost pressure, turbine changes etc.....I am just saying, beware.

 

is that why i did 591whp and 477wtrq on an unported head with their billet wheel??

 

that was on race gas tho... everyone has seen how slow the spool is on your 93 tune

 

turbo technology does seem to be advancing by leaps and bounds

 

^ true that. can wait til some of this new technology works its way into oem vehicles!

 

lol thats cause i posted a video from a 30 roll in second. go ask the guy in the gt500 how my turbo spool is. and my pump gas, still did 443 on 91octane.

 

This is gonna be exciting, turbo cars are gonna start making stupid power at stock trim level, while still getting great mpgs

 

Do you have a comparison on the same octane, boost and tune as the cast wheel?

 

on my car no. but when ryan was running the same turbo on his car he had the cast wheel. so between our cars yes, slightly

ryans car:
ported head
race gas
20psi
s262 cast wheel
think it was a little over 490whp.

my car:
unported head
91octane
20psi
s262 billet wheel
443whp

 

... that comparison is not even close.. needs to be done on same car also.. no 2 motors will act exactly the same

 

my engine is his old one... but youre right its not a 100% comparison. but still, ONLY 50whp more by going racegas and a ported head. on the same psi... come on now... tell me that has nothing to do with the difference in wheels.

 

My wheel is a billet wheel lol!! hahah It is !!!! BUT MARKS A GOOD GUY NO **** TALKING PEOPLE!!!!

 

difference in tune =p

 

lol are people really that blind on here??

 

Dude you know me. Im not stupid in these areas lol!!!!!!! So yeah!!

 

Your a liar bro. Your car didn't make that much power

 

oh and iirc we did do a race gas pull on 20psi and hit around 505-510 i think. i don't have the sheet. but still. tell me the difference isn't in the wheel when a car on race gas and a ported head does 490 on a cast wheel. and a car on an unported head and 91 does 443 on a billet wheel.

hahahahah gtfo.

 

Stop. Enough difference right there to cause skewed results. Apples to oranges. I am no young buck or beginner in this industry either. I have been around this block before.

 

lol mkay if you say so. but this thread isn't about our cars anyways is about the test car that kept everything the same but the compressor wheels.

 

lmMotherfao. hahahahahaahah

 

ps. dezod, the Batmowheel GT4202 just outflowed the stock garrett gt4202 by 60cfm at 30psi.

 

Hey Mark guess what?????????????? I ordered a new boost leak tester ahahahahahahahahaahahahahahahahahah. why you ask, because i fu**in did.... Anywho did you ever figure your car out!???????
