Has anyone installed these yet, or can vouch for the HP gains they put out?

I would mind dusting off the my engine hoist if they make high gains..

 

no one knows what they make not even zpi


but let me know when your done intstalling yours

 

you should be able to expect at least 20 but depending on your current mods its possible to gain up to 30.

 

isnt the new 06' si running on 11.1 : 1 compression ratio? and as soon as i see dyno proven results, i may get this

 

I asked the same question on ZPI's forum and this is the rely Nester left:

"We'll have sheets this week, but the car also has a host of other things.."

Hopefully the host of other things has to do with a cam shaft...

 

we have a car here going to the dyno on monday with 11.1 and our stage 1 head....short ram intake 100% stock exhaust so we will see some real world numbers very soon

 

cant wait just 3 and a half more years of warrenty then i can pick these up and do a rebuild while im at it

 

Any numbers yet?

 

yeah any numbers yet?

 

Interesting, I'd like to see these numbers as well

 

I saw on ZPI's forum that the car made 45 whp over stock.
