Lt4 tensioner vs Lt5 tensioner
To use 10pk belt, I am purchasing LT5 stuff which is using 11 ribs. Somehow the idlers from Whipple are having some problems with high speed rev or high torque? While the genuine lt4 idlers are ok from Meggi 2300. |

How long have you been using the LT5 tensioner? Any issues?

is the bolt pattern the same on the tensioner? plug n play? I was going to do that same upgrade but the guy at scoggin dickey had them in his hand over the phone and said the pattern was different. the LT5 pulleys are pretty darn cheap to swap out didn't know if it was just that simple... what's all needed?, I assume... Lt5 tensioner LT5 idlers (or just buy the smooth pulley w bearings in them a bearing store by gates or dayco and a longer bolt. 10 rib blower pulley (edelbrock has them) 10 rib ATI lower. 10 rib belt, I noticed the belt sizes get pretty far and between on the gates site I think 10 is ok but 11 and 12 few choices..

Also, for what it’s worth, the Whipple tensioner is an OEM LT4 tensioner. The original post in this thread has that incorrect. My thoughts are that the LT4 tensioner was designed for 8 ribs and when you use it on 10 ribs the tension per rib is less, leading to unsatisfactory performance at top level blower speeds. The LT5 was designed for 11 ribs so it should rock and roll on a 10 rib belt.

I paid $1K for all of it. Big 10-rib lower pulley, bracket, tensioners, new idlers, etc. Comes as a kit. Edit: here you go. https://toohighpsi.com/products/cama...s-lower-pulley

I love mine and have been running the toohighpsi tensioner pulley system and the Port Injection system since late August. Easy install and killer looks. Not running high boost but if I ever do I don't need to worry about slipping. Josh, hope your belts show tomorrow, making some boost for sure.

No problem
Order the griptec blower pulley direct from ZPE. Griptec is the only way to fly IMO. Edit: here you go. https://zpegriptec.com/
