Typically a 2.4 on one pump will go to something like 560 on E85 (fresh pump) on the Black. I was surprised I was able to push it that far. This car will get twins before too long and some dyno queen action to see whats possible for drag racing and time attack. Normally it will be run between 490 and 540 for track days.
Mikey's car made 675 on 1450s and dual 255s (inline I might add) with just enough room left it would have made something like 710 and been out. There is more to that though since its a combo of motor and compression making the available fuel work harder. We switched to an 040 and 044 for his 748 in parallel.

But two different cars two different days is a bit much.. Either way the difference is quite large..Mabye I will give it a shot on my own car and get some same car same day results.. Thanks again to ER for sharing the data. JMF makes killer products and I use/reccomend them whenever I can!
This is why I said its at least 40-50whp normally though and feel confident with that for sure.

Speaking of turbojunkie's car one of my customers ended up buying it.. We already had it on the dyno and it has a new max lock rear installed.. It's a pretty clean car.. We ended up making a few more hp out of her with a new WGA and adjustment..Any idea what that car weighs?
We didnt push the pump tune, it was primarily an E85 car so we left it that way 99.9% of the time. The 406 it made at 25psi was near the limit for 92 octane and 9.5:1 and as much as Billy was interested in presale.

I hear ya, he mainly just wanted it checked. It ran pretty good when it got here and was looking for suggestions on getting more out of it.. There wasn't much on the table when it got here.. Switching an E85 car to pump kills kittens.

I recently ran a test on my new setup to see if there were any effects based on wastegate recirculation. So what were the results? Absolutely no affect on hp or torque for this setup.
Please see the before and after setup below.

Curious if this was on a dyno? I think the difference might be the fact that its not a stock housing but its interesting that were no gains. On a 3586 we saw 40whp but some of that might have been the angle of merge when it was recirculated was less than optimal.

VDR is close enough that if it didnt show anything your setup must be very efficient recirculated obviously.
We have seen tremendous gains on the dyno and its something you definitely can feel. I doubt that VDR would miss it on the street.
