What 70 to run?

[FastRegalWE2]

car will see good amount of street duty, but will go to the track too.
ported stock big valve heads, ported intake, 3200 stall, 70mm TB and plenum, 83# inj

If you are only going to use a 3200 stall converter, then I suggest that you go with a GT67. A true 70mm turbo will need more than 3200 stall. More like 36 to 3800 in my opinion. On a track car stall should be 3800-4000.

Double ball bearing P trim will work fine.

GT70 or LT70 BB?

Turbonetics BB70Q .82 will work. I like to see 3500 for the Q but I had a 3200 Vig for a while and it was fine.

 

[salvageV6]

Innovative GT70 p trim.

Or call Jack and see what Turbonetics model will work single BB.

Or listen to Russ's recommendation above.

Spoke with John Craig in Feb.. He wouldn't build a BB turbo. Call Jack Cotton for a T-netics.

russ, is a 3500 for a BB72Q w/a.81 a perfect combo? hows the spool on it? how long would it take it to spool from dead idle time and distance-wise?

 

[REDS HOT AIR]

spool-up depends alot on how the motor is built

you want street fun stick with 70 p-trim if you want good mph go q-trim

70 with an s-trim would be sick tho

or a trillion mm with a Z trim and 100:1 housing, thatd be insane!!!!!!!!!!!!!!!! sickkkkkkkkk!!!!!

I don't know about perfect but that will work pretty well. It won't spool like a smaller turbo/combo but you'll need that little lag time to prepare for the heart attack you'll get when it hits........

Red said it best, P-trim is best for the street, Q-trim works on the street (I run a Q) but is more at home at the track. The P-trim is underrated and will for the most part be all you can handle on any street......

I had a twin turbo weed-eater running those units. It was sweet!

I was at the track rental last week with you guys. I just recieved my T-70 BB, P-trim from Jack Cotton. Give him a little business for driving down to help us. I had a TE67 (GT67mm comperssor wheel, P-trim). It did not like high boost. Power stopped at 26PSI. No gains after that. The Turbonetics unit looks bad azz.
