video of my blowerworks build c4.
Heres a youtube video of what Im working on tweaking around with now. Ive got it tuned real conservatively (19 degrees max spark advance and 10.5:1 AFR) as I make sure everything is working properly
Thank you to Greg@blowerworks for the tremendous customer service and support.
I est. about 525 rwHp and 475 rwTQ - once I get all tuned correctly.

note: ive since added the following changes since this video.
1. got rid of procharger intercooler since its more a flow restriction (doing so increased boost from 7.5 psi to 10 psi w/ same size pulley)
2. replaced stock 48mm TB with an AS&M monoblade TB.
3. put in a 4 gallon meth tank (in the rear w/ filler next to gas cap) vs. the 1 gallon washer reservoir.
4. added wideband o2 sensor data referencing capability via AC pressure sender
5. Built a bigger air box and had a custom, bigger K&N air filter installed
mod list:
1993 corvette convertible, zf6, 60000 miles
6 point roll bar
P600B @ 10 psi boost (3" diameter pulley)
8 rib custom blowerworks dedicated drive system
Blowerworks ATI 6+8 superdamper harmonic balancer keyed to crank
Blowerworks 'gaseous intercooling' kit (meth kit) w/ pressure solenoid
mildly ported lt1 heads
218/228 @ .050 hotcam kit .525/.525 w/ 1.6 roller rockers
custom 'ram air' supercharger air inlet scoop and airbox
K&N custom 4" long by 5" wide cylindrical air filter.
TPIS long tube headers
60 lb/ hr injectors (no FMU)
walbro 255 l/hr in tankpump with hotwire mod
ostrich w/ blowerworks base tune
MSD 6 BTM
AEM UEGO wideband O2 sensor
Autometer electric boost pressure gage
Autometer electric fuel pressure gage
NGK TR6? gapped at .040
Taylor spark plug wires
Fidanza lightweight aluminum flywheel
SPEC stage III+ clutch
Hurst short throw shifter
Baer 13" eradispeed rotors (front)
Hawk HP + pads
DRM brake bias spring
Earls stainless braided brake lines
1996 corvette grandsport rims (OE)
Kumho V700 P275/45R17 fronts
Kumho V700 P315/35R17 rears
Daniel Stern Bosch e-spec headlights w/ 130 watt high beams.
Note: stock pistons and compression.
My goal is to see if I can make the stock motor last a few years and then build a forged 383 monster w/ ported aftermarket heads. Im even considering adding nitrous too on a window switch. I may spray a small 50 HP shot, at the starting line, and then have it kick off at 4000 RPM. The goal will be to provide starting line torque (to prevent bogs) and cool stuff down before letting the supercharger take over for high RPM stuff.

Nice combination. Who is the vendor on the 6-point roll bar?
Dude, if that's a stock bottom-end LT1 I strongly doubt that you're at 525rwhp.
I ran a completely stock LT1 (totally stock internals) with stock exhaust manifold, no intercooling, vortech intake track, 8-rib, 60# injectors, and 9psi... the combination put down 412rwhp on a mustang dyno (ADS of Chandler, AZ). That was with a vortech T-trim head unit (larger than the p600 you've got).
525rwhp ='s 590-620 flywheel horsepower!
When I spoke to Greg (Blowerworks) and even TJ Wong, they said the most powerful (t-trim) c4 they had dyno'ed was a 383 with a healthy cam, AFR heads, no cats, and put down something like 650rwhp.
You've got a good combination man, don't want to be discouraging. But, the heads, cam, stock bottom-end, smaller supecharger just don't add up to 525rwhp.

You only picked up 2.5 lbs by getting rid of the intercooler?
When I spoke to ATI they estimated a 3-4 lb increse by switching to meth. This was with the P1SC not P600B.
I have been considering a larger intercooler and 8 rib setup, was hoping to pick up more than 2.5 lbs.
Also, did you notice any gains with the new throttle body, did you log yyou mass airflow increases?

[QUOTE=mnstrlt1;1575256027]Nice combination. Who is the vendor on the 6-point roll bar?
A guy in streetsboro, oh, did all the work at a decent price ($1k). He put the interior back together around it without butchering things up. [QUOTE]
The only down side, I thought it would add more structural rigidity - around corners than it did.
I'll have to dyno it and see, when I had a slipping belt on my p600b, smaller throttle body, procharger intercooler, and 15 degrees of timing taken out - due to knock retard, I made 441 rwHP and 444 rwTQ. (dynojet) - after 13 prior dyno pulls ! To be honest Im lucky the thing didnt blow up on the dyno due to heat soak (due to 13 prior pulls), high spark advance (26 degrees), and no meth injection at the time!
The mustang dyno's notoriously read 10-15% lower than a dyno jet.
P600b is not a small blower, it has a 1200 cfm output, just like t-trim.
Sure its not a D1-SC (1400 cfm), or the much vaunted vortech YSi / F1-R units, but its not a slouch either. Its only real issue is its crappy 3.10:1 step up ratio requiring a small pulley to make big power.
On the flipside, you will hear less about people blowing supercharger parts all over the place on a p600b. Many people have many thosands (procharger says even 100000+ miles) on the p600b without any issues. Its gotten a reputation as being extremely reliable.

I stand corrected, the P600B does flow the same as the P1SC, it's the step-up ratio that I was recalling and I was also confusing the P600B with the smaller Vortech head units (V-1/V-2 s-trim's). However, the step up ratio on the P600B (3.05:1) is an issue that I recall other owners having (belt wrap, belt slip, pulley size restrictions).
Regardless, the numbers that you put down with the previous combination are respectable! that's still 530+ flywheel horsepower! But still, with the minimal changes, you think you jumped 100+flywheel horsepower? If you can, dyno #'s would be awesome!

I think my 1993 lt1 is some magical engine built by magical people. Not a monday or 'friday' built motor. The batches of steel, aluminum pistons, rods, and crank tested +15% higher then spec when they did an instron test on those steel lot samples, etc.. etc.. etc...
Actually the only thing I hope is that if it does go, it doesnt destroy my block....
I dont know if 4 bolt main lt1's are easy to come by...

Dataloggting software usually logs ac press psi so you get wideband afr in terms of ac psi. You use a conversion factor (linear) to convert to afr

Im even considering adding nitrous too on a window switch. I may spray a small 50 HP shot, at the starting line, and then have it kick off at 4000 RPM. The goal will be to provide starting line torque (to prevent bogs) and cool stuff down before letting the supercharger take over for high RPM stuff.

A window switch is an RPM based controller. It can be setup to only spray nitrous over a given RPM range. It would automatically shut off the spray at a pre-determined RPM so you don't have to. Using that instead of a manual pushbutton will increase consistency.
