Blower shop XR1 14/71 performance

Yes thank you , I know top fuel is different than alchohol but that still says something of the potential, I would like to hear from someone that has had the same success on alchohol.

 

Ditto, mike

 

I have recently purchased a new 14-71 TBS XR1 HH. Have not got it running yet. I am not trying to rotate the earth with my deal like a Promod. I am trying to make as much power as I can at a lower boost and OD. After I get this thing running and hit a race or two, I'll report back on my findings. My previous blower was a TBS 14-71 HH retro. No other changes will be made to my combination, so it should be a good comparison.

BTW it looks like the rotors on the XR1 are set back about an inch, inch and a half more than on an M4.

 

That may be true, Mike. Like the OP, I just wonder if anyone has tried one. I'm guessing that a top of the line DPME, Fowler, etc that also costs considerably more might outperform the TBS, but until someone actually tries one we just don't know.

Not being in the Promod "circles" I gathered all the info I could before purchasing this blower, I talked to DPME, PSI, Fowler and Littlefield. I also spoke to Eddie Knox who runs this blower on his record holding T/F hydro, he did see a small performance and durability improvement over his previous blower, which was one of those mentioned above. While I'm sure I couldn't go wrong with any of the above mentioned blowers, I decided for several reasons I can't go into here to go with the TBS. Is it the absolute best tool for the job? Maybe not. But for my intended use it's pretty much overkill anyways. That being said, I won't be a big help to any of the Promod guys with me "testing" the XR1 because I'll be running a much lower boost and engine RPM range than they do and I have not run any of the other blowers mentioned. But I will report back on how this all works out.

 

No offense Mike, I respect your knowledge, and don't want to sound like a smart ass, and are also as guilty as the next guy, but maybe if someone would try something different and not be so much monkey see monkey do person, we might find out there is something better. I'm convinced thats why guys come from Sweden and Australia kick our asses because they are doing things different to their parts and cars as well as running them in ways a little away from ordinary.
Maybe no top runners are using these blowers because because they are convinced that they have the best there is already.

I'll agree with that, apples to oranges.

But it does show that they build a good piece, don't you think?

 

I spoke to Eddie, they are allowed to and do run a High Helix blower FWIW.

 

I was surprised they can run a HH blower. I'll agree, running nitro and being a boat would be quite different from alcohol and asphalt

 

NOPE

 

Maybe someday..........................

I did hear from The Blower Shop that there are some pullers running them, don't know who though.

 

Here's the latest, this blower is now on my 540 12° BBC. At 9% OD it's making 24.5#@8000 RPM. I have very little stagger in the port nozzles, egt's and plugs very even front to rear. The blower is not setback, just bolted to the Indy intake. Don't have an intake air temperature sensor, so don't know about that. Just went 3.80 lifting .5 before the stripe, car weighs 1960#.

 

You must be in Bradenton .

 

I was, home now......

 

Mine is a HH.

 

Eddie Knox told me they are running 50+ boost. They can and do run a HH.
