Here's my dyno sheet with the wastegate set up as a comparison

Interesting, your low/mid torque numbers are slightly lower that what I've seen. Usually I see 400wtq being hit at 4.0K RPMs.

Not sure if this graph will help any one out. My tuner was was a bit unfamiliar of how to bleed off boost on this setup. Took four tries before he got it figured out.This was on 93 and as you can see the S/C appears to kick in at about 3700 or so.he had a boost cut at 15 psi and was getting it dial in at about 9.5. So first four runs peak boost of 15 psi at about 5500 to 5700 rpm.Last run was finally at 9.5psi.

Guys please keep in mine that when you are getting on it your cars rpm will drop down to 5000 to 5500 hundred depending on the gear.So Any power behind that is something you will never really use unless your in first gear.This is where you guys with rev match transmission can shine because of boost by gear. No boost on first gear would be great because who can really run 600whp in that gear without spinning. Unless you have a killer setup. Anyway everyone has different goals so come the different views. Hopefully this graph helps on how this efficient this kit is. Almost forgot the whp is predictable with more psi but we noticed the torque curve hold way longer(doesn't drop off)throughout the powerband.

You really need to display the boost graph vs the afrs. Afrs mean nothing here where psi is what we are looking for. I know it's difficult to obtain them. I've been to 50 dyno sessions over 20 tuners and getting them to print or send you what you ask for is like pulling teeth!!! It's been a mystery to me and my buds since I started into cars.. lol. ��


However what we can see from your graph is that the cars performance is almost identical up to 4500rpm weather your running 10psi map or 17psi. Again, mid range power is way up from other centrifugal chargers. If you were running a different centri charger kit you wouldn't see 10psi until redline and the power band would follow suit being lower.

:facepalm: My bad, nice numbers! Your low end (<3K) looks great too! Was that on e85 or 93?

That was the same blower as the previous dyno sheet but a smaller sc pulley and on e85

I can't recall but I think Redondo's oil slinger ate itself apart around 17psi...? I know Soho did a write up where it starts to spit oil out at 18psi. From what I've seen anything over 15psi puts that unit on a yearly rebuild list. Past that the oil slinger cavitates the oil and turns it into a froth not allowing proper cooling since it is self contained. That's when things go bad. (Straight from Vortech).

That's lots of little secrets but can't spill them all.

We are actually creating 3 different pulley setups now. You will be able to select the standard set, race set or Max set. We need to test these still but the max setup will come with Carbonite coated pulleys and cost more but will be reserved for built motors only.

Check out Carbonite coatings if you haven't seen or heard of it. There's also a high grip option called reichard.

We will always strive to improve. Most of the time I'm not even sure what that is until it happens. Lol .

Love what you've done with the C38R on this platform btw. Uploaded is a dynongraph on what the C38R does on a 3.7L Honda single cam V6 for comparison. The C38R is a beast in such a small package
