haha nice job! I have just over 2k mi on the GT45. Have a few questions for you bobybeach. Thru PM

 

haha i better get my self a nice hot coco then and get comfortable let im rip!

 

hi would this turbo work well with the 20b engine. I have MP turbo serial number 805090 A/R .70. can anyone tell wats the maximum bhp i can get out of it or shall i stick with t51spl or t62.

regards

 

i also have a mp t70.. trying to wrap up some loose ends on the setup.. hoping to see some decent numbers...

 

Guys any advise on maximum BHP out of Ar .70....

 

Are you referring to the hotside A/R or the compressor housing? The compressor housing is .70 and that is always matched to the compressor wheel, it's not really a measurement that changes or means a whole lot.

If that is the turbine A/R then it's too small for a rotary. If that isn't the turbine a/r measurement then you need to find out what yours is. A MP t70 would probably work well with the 20b, depends on your power goals.

looking at the following link it appears that masterpower does have a .70 T3 turbine housing option. If that's the housing you have it's way too small.

I would use something a lot larger for a 20B, Syed.

.96a/r for the hotside is basically the standard size for rotary engines, going smaller chokes the engine up for less power and slightly faster spool and larger gets you more top end power in exchange for quicker spooling.

the T-70 is good for around 600WHP at about 28psi with the right turbine housing and engine setup on a 13B engine.

 

Thanx guys for your info...I think I would stick with my Greddy T8834d then...as soon I am going to upgrade my turbo to T62R.....

Cheers guys

 

Anyone what any mp T70 dyno sheets?

A few guys have said they max out at around 500whp & 20-25psi.

 

Not yet but I hope to pretty soon. Still have a couple things to get for the car then I'll park it on the dyno.

Cool, which turbine wheel and housing are you using?

How much boost do you plan on running and what #'s are you aiming for?

 

hey just wondering, a decent amount of people running these, how come nobody posted a dyno graph yet?

 

Hey BDC

Did you end up making it to the dyno?
