I am looking to see what kind of power people are making with Inline Pro Valvetrain. I have a head here, and i want to see what kind of RPM and power limitations there are with this valvetrain.

Thanks in advance

we have been making 640whp on one of our cars for 1 year using the inline pro springs/retainers and oem valves with no issues revving the car to 10k. the price is good too.

anyone have any other input?

 

I have their springs and retainers + stock valves & cams on a mild build and rev to 9000 on a B16A head. I've had them for over a year, but don't do it all the time.

 

you can't go wrong with most of the valvetrain on the market nowadays. though for longetivity, you should look for the springs that are less harsh on wear, yet can rev high simaltaneously.

 

we used them in alot of our turbo 500+ whp cars w/ zero problems

 

I use them in my turbo b18 and no problems
