I'm planning on grabbing the M7 2% crank pulley. i was wonding if i should hav any problems since i have the Auto??

I dont see the difference in if i was ging to get the 17% supercharger pulley.

anyway i have the 15% supercharger pulley already.

any insight?

thanks!

 

I did read somethere that one guy did have a 2% on his auto and took it off. I think it may have been in the 2% crank survey thread where there's a table of people with different combos of pulleys and whether they had issues or not.

I think that this person said he/she said the engine wasn't reading the revs right since the harmonics of the engine are changed. This makes sense for an auto, for sure.

I myself have PMed several people about theirs and for the most part there are not many problems (for manuals) but several didn't think it was really worth it to spend $150+$100 for install, give or take...for only a small change.

 

yeah thats what i saw. but is he the only guy thats put the crank pulley on the auto?

Maybe I'll ask M7...

 

I doubt he is the ONLY one...

I emailed both ALTA and M7 about the 2% and both were very helpful.

 

awesome i sent them an email. just waiting for a response

thanks!

 

 

i have a 16% m7 + 2% M7 crank pulley and never faces a problem

 

good to know. thanks man!

 

I've got a 17% and a 2% pulley on my auto with no problems so far anyway.
