Strapped the car down this week to try and get a full pull to get a log and boost amount on my setup. My boost gauge seems to be inaccurate on my dakota digital stuff. Also finally found my false knock issues coming from the metal hood tapping on the procharger head unit.

Setup is a GenII crate motor (93oct)
P1x with 4.5" pulley stage 2 setup with big FMIC
2018 (non-ported intake mani) CMCV lockouts
Full length headers with 3" exhaust
Single walbro (e85 capable) intake pump with -6 feed/return
ID1050's
Lund doing the tuning (big shout out to him for great tuning and awesome service)
TKO600
9" Rear

We got some wheel spin on the first pass and on this pass (video below) may have spun a bit at the top 7k to 7600rpms when we let off, but dyno only read up to 6900rpm. Definitely has more with the graph still shooting up.
Peaked at 10.7psi
614rwhp @6900
475rwtq (don't mind the comments tq number lol, I wish)

Because we all can't leave well enough alone :) I think it's time to do e85 and even pulley down. I'll add another intank pump and increase the fuel line size, but unsure of what pulley I should move to.
Adding timing with e85 should get me some good gains, and since I'll have to do a re-tune, might as well add some boost.

Any thoughts on pulley size to get me a few more pounds of boost? That said, consideration I'm on stock motor with stock op/timing gears. I suppose the goal would be around high 700rwhp.

That should be an absolute monster... What's it weigh? 3100? Are you using a factory pcm or a crate motor pcm? I have a 71 Plymouth sitting around with no motor, tk0-600, dana, mini tubbed and roll caged that I really should do this too..

It definitely moves out as the boost climbs. With me in it, 3220lbs! I am using the Ford Control pack and SCT x4 to load the tunes/log. I do need to mini tub this thing over the winter though, these tires are just too small for the track. On the street with the nice linear output of the blower it hooks pretty good (once the tires are warm)

That would be a wicked setup in that 71! Would love to see that.

I’d drop one more pulley size, swap the proflo bov if that’s what it has, go E85. And put a Mak Performance inlet on it.

That should put you at around 730ishWHP.

This would help a lot, especially since you're only pulling to 7k, you're barely starting to get to the powerband on that blower. You'll get a lot more torque too.

First off absolutely love that car!!!!
For comparison....comparing apples for apples - Procharger - boost is boost
Gen 2 motor as well - stock internals - including opg and cs.
First setup I had was P1SC-1 and at 10.5 lbs on a 3.7" pulley the car was at 630/495 at 7300rpm.
Same setup on E85 710/540. The P1X flows more CFM so going down in pulley size is not exactly the same.
10.5ish is about ALL you should go on 93. With stock internals 14-15psi would be max IMO.
If you ever want to talk trades - 2015 , Procharged - 801/595 - Iowa - let me know.. :like:

So go with a 4.38 pulley? can I use my same belt? K080660HD
I've seen others swap out to a different bov, I'm using the proflo one that came with it, what results have others seen on the other ones, like Tial,etc.. more boost?

Appreciate the feedback guys as well as compliments on the car, it is a blast for sure. I think that extra tq/power from the e85 and a tick more boost would scratch the itch and keep me in safe with the stock motor and clutch/trans setup too. Swapping to a vbanded bov will help me with some clearance as an added bonus too. I'll start collecting the parts for a winter update.

One more pic for good measure :)

That's a beautiful and worthy project. You've done a great Job. It makes me feel bad I gave up on my '68 when I bought my S550.

Well, I broke out of the house yesterday to log and tune the car on e85 and the 4.38 pulley. First off, thanks to Lund for the support and great service!
So I added a fuel pump (2 walbro hellcat pumps), increased the feed line from -6 to -8 and a dedicated e85 tune from Jon. The pump e85 I got was at about 80% ethanol (oddly my innovative ethanol gauge was only showing 70%) so I added a few gallons of e98 for safe measure :)

Couple of tune tweaks and ended the day very happy. The final numbers were
789rwqhp
618rwtq
boost on my gauge showed around 13psi (dyno boost ref spiked a bit so it shows 15 on the chart below)
I'll have a video soon of the pull but here is the graph.
