On the 102 & above you better have a EXCELLENT tuner on the hp tuners. If not you will be taking it off & selling it I know they give you the paper for the % on it to do this & do that. But still need a lot of help for the normal street part of that big T.B. The 95 will be all I am going with on my new forged build. Robert

I just had this conversation with MTI in Houston. They had a lot of good input on it. Iíll see if they can post up their findings.

The 95 zr1 t,b, would be the one I would am going with on my new build. I have seen so much problem on the bigger one on the street tune in having problems.

I went with the zr1 tb. I think it should be good enough for the z06 blower. Plus I got everything for around $250 and I opened the snout with drill and sandpaper roll. Just waiting on MTI's fuel system then a dyno tune.

The 103 is the best. A PD blower wants as much air as it can get.

Katech 103mm on my G1Pro intake for my Procharger nothing but positive to report. Thought I may have caused idle issues but that was a restrictive filter Procharger sent me. Soon as I put a big green filter on itís idling fine. The Katech TB is beautiful also a nice billet piece. I know that sucker letís a lot more air in just look at it side by side.

Robert couldn't have said it better myself it's all about the tuner. Chris has spent some time and numerous adjustments to get mine to a point I am getting satisfied. The more radical the build the harder it is to tune in most cases. I chose Chris b/c he has so much experience with port injection and builds similar to mine. Can't say enough about the guy! It's also good to chat with ya Robert being a fellow C5'er myself! That's where my madness started and I am sure you spent some money in those days as well!

Told myself wasn't going to mod this c7 on perdurance side at all. Well that when to HEL*. All new beefed up rear end axles half shaft, now new stock c.i. all forged new motor, ported heads, cam, small cam BTR stage II set up, small A/A TI blower with the smallest pulley can get, LT4 inj & pump. Call this it on the motor not even close to the c5. But with all the after market parts on this c7 should be safe around 800 plus RWHP. We will see what happens.

From what I saw from installing the 1.7 is a little too small for the 95tb. Where the 2300 uses the 95tb extra air and also so it fits nicely. I would buy the MAMO or Katech ported for the 1.7.

The trouble with that is you run in to the big O ring if you port much at all the oring is smaller than the 95tb on the 1.7.
I did sorta like the top end with the 95 felt it did add a little top HPto the 1.7 . But it is great on the 2300.

I was able too port match the 95mm spacer and still have the o ring . It is close. I can see if you port to much it will mess up the o ring groove.

No, just What you see. I wouldn't know how to port the snout. I just wanted the opening to be the same size as the tb. I think you would have a blade interference if you don't port match. Here is a pic before I started.

The 95mm LT5 is a great option and we should have ported systems available soon. However, the 103s are crucial for big power set ups with ported blowers. It's pretty simple to tune for them, we have never had a drivability issue with one but it will need to be tuned for sure. We have seen major gains with our Jokers Chaos ported LT4 and the 103s.
