vortech pulley sizes ?

Recommended Posts

Hi all ,

 

just wandered what the differnt pulley sizes equate to in bhp/ftlb gain on the vortech supercharger unit ? and what do most people run? Thanks :)

I'm running the 3.12" pulley.

 

The gains will vary from car to car (engine to engine) somewhat I'd imagine but from what I gather the one I'm running will gain around 25whp over the standard 3.33" pulley. This info is from the "Vortech FAQs" thread on "my350.com".

Take your time and have a good read of that thread as it will probably answer any questions you have regarding the Vortech superchargers. :thumbs:

Well i read most of it and came to the conclusion that the vortech blowers and the zed engine are a great combo ! ...... and also ill be getting the 3.12 pulley ..... even though i havent even driven my 435bhp zed yet!

Come on you never read "most" of that. :dry::lol:

 

It's 112 pages long, ...if you read all of that in ten minutes though fair play. :D Some of the posts from the US guys running Vortech's do have some interesting insights into problems & solutions.

 

Is yours all done then now? :shrug:

No i read the first few pages from the bloke who new what he was going on about :)

 

jez mapped it yesterday ... but still needs to map the idle and cold start , plus a few other bits and bobs . Ill probably run it as it is for a bit to make sure its all good and then get the smaller pulley for the icing on thye cake :)

 

would really like to make 450 ! .... just seems a nice number :)

Ha ha , yes should do that really !!

Just nice to know I've got the option of another ( relatively ) easy 20bhp gain

Yep I agree.

 

The 2.87" pulley though apparently makes 30whp over the 3.12" so if you skipped the 3.12" and went straight to the 2.87" that's supposed to be around an extra 50whp over the standard 3.33". :teeth:

 

Bearing in mind though it might not be too clever for the standard engine internals pushing them too far.

:lol: DE on 2.87 pushed to 7000 RPM.. I'm sure Zmanalex has a quality second hand engine available to fix the certain devastation :lol:

Would still run the risk of going bang again, ...best way forward then would be a forged rebuild. :evil:

I think we need to take josh back to all those nice safe references he made before doing the FI lol

:lol:

 

That may be a good idea. :teeth:

GM, you're very helpful tonight, do you envy his car or what? Stop giving him ideas! :lol: :lol:

I'm always helpful (well imho). :):wave:

 

I think he's got his own ideas, ...probably been tuning up a 350Z on "Gran Turismo 6" on the PS3 and seen that you can get 600bhp odd. :lol::drive1
