How does it feel??? The response is really smooth boost slides right in. It's not jary at all. Super smooth. It forces you back into the seat with authority and doesn't let go. There is absolutely 0 lag time while switching gears. It is very quick. Aside from the numbers, it is exactly what I wanted. Very usable power. The power band is perfect for what I use it for . All I can say is this sucker moves out in a hurry.

AHHHHH, that makes sense.......very sweet though! I'm glad you're finally happy with it......its bout damn time. So I wanna ride now! tell ya what.....we'll swap rides when I get my turbo installed
.....that will give me incentive to get 'er done! Although I still gotta save up for my accessport and tune. <sigh>-Ted

Congrats on everything turning out ok!
I was planning on a similar setup as yours; after Ed showed me your dyno graph I don't think I'll be keeping the vf30 anymore if even a td06 drops off like that
or maybe it's just the stock cams...

Jeff, thanks for the nice review. I agree the numbers seem a bit low for the setup, but without an EGT gauge I did not feel comfortable running any leaner than 10.8:1 on your brand new short block. The turbo is deffinately out of breath above 5k RPM and the setup would not take any more ignitiona advance. It did respond fairly well to a/f changes, however, so as long as your EGT's are controllable with a leaner a/f, we should be able to get a bit more power out of it. I do agree that this turbo is a bit on the small side for the motor but Jeff is after great response and lots of low end for the twisties and he deffinately got that.
Thanks
Thanks

Last night I opened the doors and allowed a few in for a ride. Even with four of us in there it pulled and made an impression. Not as fun as solo or doubled up but a nice hard pull none the less. I'll be shopping for an EGT.

mmmmm defi.....mmmmmm.
yeah those numbers kind of got me wondering what the hell FLI was doing to the motor to get 310 or how off the dyno really is.
Can't wait to see that thing with an EGT in there, broke in a bit more and put on a dyno.
I really was expections something closer to 300/325 but you can't complain about DOUBLING your torque numbers..haaaa.
oh and jeff...think I found where it's leaking. Valve cover gasket or something back by the pcv but that doesn't explain the weird noise. It's going in next week.

BTW, comparing numbers from FLI's dyno with these is pretty useless. I don't think we have seen any real baseline numbers come off their dyno so there is no way to tell how its readings compare. Look at Cobb's Mustang Dyno for example... it reads extremely optimistically and is much closer to DynoJet numbers.
Thanks
