We can arrange that. We can even provide for Turbowski if he needs to come and fix your mess

He wants the worse of the two give him a break

You should add in the % from max revolution, at the same rpm. Vortech is 86% @ 7,400RPM. 7,400 would be an ideal RPM for comparison.

I forget what % the others are at. I think this really matters for those of us that want the 300+WHP range and want to get an idea where most kits will max out.

Should we include the possible numbers for the larger blower possible with the KW kit too? Nope doesn't matter. I think the point of this is what the out of the box kit can do with a proper tune.

Using this post at reference:
Jackson Racing @7,400RPM: 90.6%
Kraftwerks @7,400RPM: 93.4%
Vortech @7,400RPM: 86.0%

The fact that a unit is upgradeable is something worth mentioning. But if your looking for what each kit is potentially able to push out then finding out what the max power @ a max revolution would also matter. Considering the fact that the vortech is able to keep up with the KW kit for most of the RPM band with only 86% of its headroom being used vs 93% of the KW means that there is a chance it my actually perform the same if not better when at the same headroom usage. This also means that there is a chance that one blower may have the ability to make more power maxed out than another one with simply swapping pulleys.

If you want this to be an exact science the JR kit should be 100% thrown out as it was installed on a car that had a non factory exhaust. This is completely non-comparable IMO. If I can get 25-30WHP gain on an N/A car on 91 octane by removing the front cat with a quality header, that % change could potentially swing the efficiency of the JR kit more than I would be willing to accept. This along the lines of seeing what intakes make the most power. On a 100% stock car no matter what the injen typically wins. That is until the ecu's feul rims kick in and its 1AFR point shift that it causes due to MAF alteration re-enrichens the mixture. If you want a fair comparison, it should be a fair comparison, otherwise it should be noted the difference.

Stock kits:
JR impeller speed @7400: 7400x1.29x9.49 = 90,591 rpm = 90.6% rated capacity
KW impeller speed @7800: 7800x1.33x9.49 = 98,696 rpm (KW's tune redlines at 7800) = 98.7% rated capacity
Vortech impeller speed @7400 : 41,588 rpm = 83.2% rated capacity

Kits as pictured in graphs:
Jackson Racing: 90.6% - 90,591 rpm (100k max)
Kraftwerks: 93.4% - 93,401 rpm (100k max)
Vortech: 86.0% - 43,022 rpm (50k max)

I would mark each one at 7,400. I hope I dont offend by saying this but it really is starting to look like your being paid by JRSC at this point to representing them by showing the fact their kit goes to 7,800RPM. Stating that it is 93.4% spun at 7,400 shows that they are in fact spinning by a fair margin more and that lone gives more evidence. People skimming posts may see 98.7 and not read the part where it says 7,800 and may swing them to purchase the JRSC on this information alone if they are wanting to tap 300WHP.

I am just trying to provide my opinion on trying to keep everything as fair as possible.

Edit: @CSG Mike your updated posts makes it much more fair. I like the idea of putting both numbers. The fact that KW is over spinning compared to the JRSC is displayed much better by showing both values.

Not sure where the 41,588 came from... If anyone should be playing fanboy on vortech's kit it should be me. And from Brian's post he said that it is spinning at a higher rate than 41,588. He said 43,022.

@CSG Mike, toss that in the first post!

I'm looking for data on the Innovate kit, but I can't find it

Stock is a 3.60" pulley :p

I had some info on this including the compressor map... ill see if I can find it tonight but I likely misplaced it.

3.60" IIRC was on the V1 kit that they initially released. This unit struggled passing ~230-240WHP. I can verify with a caliper when I get home but i am fairly certain I had a 3.48" pulley on my kit that I purchased earlier this year. I believe this is also why they recently switched the kit to a 970 belt instead of the included 975 as the 975 was from wen the kit came with a 3.60" pulley.

Vortech also upgraded users for free if i understand correctly so the V1 kit is basically non existant at this point.
