about bullseye power t04E 50 trim

anteversion · 09-27-2008, 06:45 PM

So, im actually running a 16g turbo wich is at it max power right now. I want to upgrade with BC 272 cams and im interested about this bullseye turbo. i was wondering what you guys are thinking about it?? thanks

I have one sitting waiting to be installed. From what I read, it's rated to about 550hp and spools around 3.8k average. But that's only for the to4b compressor housing. I'm hoping it'll be better with the upgraded to4e housing. It will be a very interesting combo with the BC street/strip cams.

I've got the T04B version and, despite them sending me a faulty actuator (would only boost to 10psi), it works well. Spool seems to be a little slow at about 4,100, but maybe some tuning can bring that down.

Am using it with FP1x cams and have seen my power figures up by around 50-60whp with the change in turbo and intercooler. Pretty pleased with it so far.

The 50-trim compressor doesn't even flow 50 lb/min

. It does spool to 20ish psi under 4K as reported by many.

But you can just get the BEP housing (same as what's on that 50-trim) cut for the holset hx35 and install a used holset h1c and get faster spool and the same flow. With the same cost in oil lines. No coolant line costs. And a far less expensive turbo. Or you can spend a little more and get a used holset hx35 have 52lb/min flow (about 2-3 more than a 20g, 50-trim, h1c) and have the same spool speed.

. . . Here I go promoting holsets again.

Please don't remind me about holsets. It saddens me I didn't get one before I got my 50 trim.
