Have any of you done business with them? Results of blower porting and is it worth it? What kind of power gains are seen? Any of you choose the lightweight rotors? I did use search but looking for more current info or any from previous users/customers. Thanks all

 

call steg and ask them

 

Yea just thought others might have less biased reviews before I contacted directly lol

and so on......

 

I don't think anyone has pulled the trigger here on that yet, I know there was lots of talk when it was released.

I might have missed something tho, never know

 

Stay away from the lightweight rotors.

SVT guys had issues with them.

Their porting is nice though. Look into that.

 

Have seen those none of which offer results only useful post was powells

 

Then buy them up, dyno with stock ones, swap out the lightweights, and dyno again.

 

Again, please look into them further.

SVT guys had little luck with them.

 

Back in the day a few had it. Gains were moderate I believe.

 

stiegmeier, not even once

 

know one has had the light weight rotors that I know of but a couple spent the green for their porting services

 

Right! I meant for the whole porting and rotors.

I dunno if the gains are worth it on the m62...now on the tvs....I like the idea.

 

I don't think there would really be any gain at to justify the cost/return on getting it done even on the tvs not to mention porting the tvs you don't gain much so its not worth it and as staged has mentioned the svt guys are having problems with the rotors

it was nice to meet you at ced

 

The gains iirc back in the day where something around 5-12whp and a super slight powerband shift if that. So yeah as said, nothing really astonishing but it was there. Looked great though lol.

Has someone ported the tvs? Man its been a while since I've payed attention to them lol

We met man? **** you guys gotta tell me your screen names and real names!

 

Yea I was just curious about the rotors. Figured they were more problems then worth lol. Head work will definitely come first. Just thought extra 10-20 from m62 port couldn't hurt but wasn't sure if it would even gain that lol. Thanks guys

 

Port it yourself or get it out to Euthanasia.

 

hell yes we met you Mohawk wearing pimp I asked your car was and you were standing beside it lol

 

Im running the Steig M62 with an LS1 tb. I 'want' to say the revs were faster compared to my stock M62 but that was most likely a butt'dyno type of thing as most mods are. It also had a slightly different whine to it, still very high pitch and bad ass lol. You might benefit slightly from a venom cooler type setup (for the snout) keeping the blower cooler but from what I read a while back the lightweight rotors weren't worth the upgrade as said previously here.





and yes, I know the Teflon coating is missing, the previous owner had a meth addiction lol


and this is why I mated the ported blower with a larger tb...obvious difference in flow capabilities lol <LS1> <L61> <Vortec>

 

fyi.... not teflon coating on the rotors.... abradable coating

Other than faster revs, did you notice any difference in power?

 

of course its going to rev faster with a bigger throttle plate your pulling more air in

 

I ported my m62 based off how steigmiere does it, nets like 5whp. I also have the m62 lightweight rotors, something with tye blower was too tight got 243 whp off ported blower, lightweight rotors, and a 2.7, put old rotor pack In made 272whp. And they raised the price to $600 for lightweight rotors...

 

Staged, I couldn't tell you if my ported blower actually proved to be worth the money (I bought it already ported). My tune was so bad anything over half throttle and above 2nd gear was full rich (like my wideband only reads 10.0 on the low side and it was prob a lot lower than that). So I never had quality pulls.

Now that Im HPTuned, once the LSJ goes back in, Ill have a good solid build and tune for a proper dyno. Unfortunately, my only previous dyno was on the stock blower, stock tb, 2.8" pulley, and a REALLY rich tune which only netted 201hp/201tq. Shop said I was prob sitting on 40-60fwhp easy with a proper tune. So Im hoping to hit up the same dyno shop just to see, with my current set up and meth also going in. I don't care about numbers really, but its nice to see progress so Im going to try to make sure I hit up the same shop.

 

Is your throttle cable hook up and return spring on the top or bottom? I use the same throttle body and its size matches the blower inlet perfectly when it lines up. Mine did not until I port matched the adapter plate and blower inlet a whole lot. Looking inside past the throttle plate is when I found the mis match.

 

How much did you wind up paying for the port job, looks like for the most part it was done properly although ive seen better work elsewhere. The venom snout cooler is a joke IMO, and thats basically the same thing i keep hearing from the M112 users as well. There isnt really all that much that needs to be done that eaton hasnt already done for you from the production line. Porting in the inlet side definitely helps but the outlet side is such a delicate process sometimes the risk outweighs the benefit.
