ive looked over the page i just dont see any difference in the 2 besides the m trim is 50$ more, does anybody know the difference? i dont mind paying the 50$ extra if its worth it.

heres the link

On the Bullseye site, the M-trim is listed from 250-400 HP and the V-trim is from 300-400 HP. There's likely a small difference in the sizes of either the compressor or turbine wheel. If you can keep boost levels away from the surge line on the compressor map, the V-trim is the better option and has made 400 WHP on a properly tuned motor. Then again so has an EVO III.

Feel free to reference this thread for some additional testing results:

Lots of bolt on turbo's exist, but only a few go on as easily as a Bullseye-Power designed turbocharger. There TO4B style compressor cover can flow almost enough air for 600 horsepower, but can bolt up without the need to dent the water pipe! Inside this cover you will find a range of compressor wheels, which inside this turbocharger is a new comer, the M trim. Borg Warners M trim compressor will do well on pump gas and with a shot of race gas, the turbocharger really comes to life!

for the v trim

this is on slowbowracing, what a big help few word differences...

i have the evo 3 16g, but it seems like i have to mess with the afc everyday , it does great with a little race gas but on the street she doesnt like 20-25 psi without playing with the afc for half an hour, im lookin for a more pump friendly turbo, i will probably sell my evo turbo so it wont be much out of my pocket to get a new one and my turbo was ported.

well, thank you very much andy , im sorry i searched but became impatient

wow the evo 3 made more torque and whp then the m trim and the v trim made a little over 40 whp and 10 torque, but the evo was tested on an engine with 8.3 comp pistons instead of 8.8 . so maybe i should just stick with the evo =x

The V-trim or any 50 trim variant would be good on pump for you as you already suspected. The reason for this is that it has a larger compressor cover and generates less heat as it moves the air charge. If you want to run well on pump, it's a sound choice and the price is right. You may want to keep in mind that the AFC is part of your problem. As you pull airflow, you increase timing and that's why you're in a constant tail chase.

Good luck making your choice.

yes i know this the afc is a problematic device but at the track it works wonders, when i add a little fuel it fuel cuts when i take some out it knocks, yes ive checked for boost leaks and i do have a few but been putting off fixing them , they are before the gm maf so hopefully its not to big of an issue.

im thinking of the v trim but the statistics of the turbos made me kind of wonder a little bit, maybe i would be better off getting some cams and keeping the evo 3, o boy choices choices, i do want 400 whp though , so maybe a slightly larger turbo then all of them would suit me best, it just looks like a hell of a bank for the buck for the v or m trim.

This is a friend of mine's old car. We literally threw his setup together in like a day, tuned it for like 10 minutes, and went to the track. No cams, stock ECU, just a VPC. Full weight car, no tricks.

Unfortunately, he had tranny problems and put the car back to stock and sold it before he got to run it with the FP2s, wideband, keydiver chip, and 750s. It felt like an easy mid-120s car.
