Weistec vs Speedriven Blower
I'm planning on upgrading the blower on my E(in a few months). I'm on the fence between these two kits.
So the point of this thread is to get people with these kits to chim in. I know speedriven has a few more going on soon but only one running, so far it put down good power with no issues. Weistec on the other hand has had this kit out for awhile with a few guys running it. Some with issue's and some with good results.
What do you guys think?

Pretty sure there will only be two people on the forum that jump in and say Weistec is the one to go with. I am waiting to see the feedback on the Speed Driven kit. It looks like they may have taken the time to work out some of the kinks. I mean the ones that Weistec is still having.

We (as a general 55k industry, save for the TT guys) keep adding fuel to a fire with no oxygen. Too make solid repeatable power we likely need an IC larger than the stock location permits. I think we'll be disappointed until there's a viable option for a significantly larger IC. The speedriven kit may have less heat issues than the weistec but time will have to answer that question. I still think we're trying to move a mountain with a lever that's not nearly long enough.

I believe Speeddriven is the better unit for the simple reason that Weistec's is as not efficient. The few customers that are currently running the Weistec blower are chosing to use Meth to keep IAT's down.
I'm sorry, but a larger blower with a (supposedly) more efficient inter cooler should NOT have to rely on Meth to keep things cool.

Mercedes E55 with Whipple 2.9L supercharger - YouTube
The car is in its developmental stage. The video provided is with 10 psi pulley which it put down 500whp at a dyno jet( dyno which we have used for years) The car previously made 508whp(around 15 psi) 180 asp pulley, 82mm tb, mbh header, injectors, and a trunk tank. With 5 psi less the the new charger is it around the same power.

This is true, but the fact of the matter is, you ( or any of us) know absolutely zero about speeddrivens blower upgrade except what the guy who wants to sell it to you has told you about it.

I wasn't suggesting that. I was just excluding those builds since they didnt apply to this discussion. I'm suggesting a top mount (or anywhere but the valley) larger higher flowing more efficient intercooler setup. Think the speedriven setup with a set of TMICs. I think something along those lines is the ticket to a great supercharger build on these cars.

Tell them it's a 2008 on your tech sheet. Then you can run low tens with no bar.

I'm goin off of facts. I spoke to the owner of the one with the speedriven kit. Also when I compared dynos and other facts, I found that weistec uses 2.2 in pulley with 17 psi and sd uses a 2.5inch pulley with 17 psi. Why the difference?

If you don't do that, please run it on radials so we can see the traps.

I've heard others interpret that rule as bone stock as well, but at least around here it it means not "altered" as in cut up into an altered race car.

And Chris has it right...
BTW - Unaltered does not mean no different blower, no headers, no pulley, etc. They mean stock/oem wheelbase, frame/sheetmetal, and safety equipment as explained by the tech at my local track. The tech told me the rule book was silent on this in case the rule changes proved to be unsafe. So far, he told me that the tracks have never been so busy and the NHRA is thrilled because they feel like its a resurgance of the sport.

The rule clearly states "unaltered", not "converted into an altered". Im not sure where the confusion is except someone trying to twist the rule around.
So someone with a 2013 Smart car that came stock with 47 hp can put in a 700 hp motor and run 10.0 legally?

A low ten second late model car is so much safer without a redneck gym of bare steel pipes running throughout the interior... I'm ecstatic they made that change.
