MTI T1 (JIF) Cam Installed, Thoughts Lunati grind, MTI cam: 221/221 .558/.558 112 +4
The T1 is in the car. We've affectionantly renamed it the JIF cam (inside local F-Body joke).
Here are my thoughts on it after about 100 miles of driving.
Idle: Wow, this is really a 221/221 cam? Seriously folks? Really?
This thing may be a case of more bark than bite. It has a VERY healthy idle, sounds like a 230+ cam once the engine is warmed up and the idle drops down. A little adjusting to the idle screw and I'm idling at about 650-700 RPMs in Park with a warm engine.
Part throttle: Even after part throttle you can tell its got a little more get-up-and-go, but you'd have to be really familiar with the car. With the 4000 stall you dont really notice the power unless you go about 65-75% throttle or more.
WOT: I went from a car with a lid, cutout, 3200 stall and 3.42s and added long tubes, true duals, cam and 4000 stall. As soon as I go WOT the RPMs shoot up there. 1st gear at WOT is useless. Hit it anywhere from 50-65 and it throws you in the seat and takes off. Shift extension around 5100-5200 factory tach indicated. Hitting it so it'll drop into second then staying in it through the shift and into third feels awesome. The car really moves.
All this is untuned save a little tuning for codes. I'll be one happy camper after a dyno tune and if I can get this damn TCI converter to lock.
Very happy with the cam though. I will give it this, the car is LOUD now, so it might be time to look into some Borla XR1s or Magnaflow 4x9 full size mufflers to quiet this beast down a bit. These Spiral Flows are ridiculous now.

What exactly is it that makes that cam (or any cam) sound so bad-*** without being a 234/238 or something ? I have a similar MTI (Lunati) grind also not on XER lobe and it is more civil (222/222 566/566 112) that the T1.

This is the Lunati grind T1, so I dont think it's on XE-R lobes. I thought I heard it had lazy lobes on it and thats was part of the reason it chopped like it did. Regardless I'm still loving it. After having my shift points bumped up a bit so I can wind the car out a little more it's really a nice little cam. Now I am wanting a monster though just for the extra power (G5X3 would be nice ), but that'll come down the road when I build a new motor for the car.

The T1 is an old school cam it is NOT on XER lobes. I almost got that cam right before the exposion w/ the bigger cams w/ xer lobes and much better tuning abilities w/Edit. Then MTI stopped selling it but you can still get it from Lunati.
JRP Summed it up in the sticky BTW:"If you know the advertised duration (.006) of a cam you can calculate the ramp rate. To do this you take the duration @.006 and subtract it from the duration @ .050. A number of 53 or higher denotes an XE lobe or other mild lobe and a number of 49 or lower denotes an XE-R lobe or other aggressive lobe..."
T1: 281 (.006) – 221 (.050) = 59

Glad you like it. I will putting this same in my 5.3 but the MTI B1. This is the same cam but it's the 114 lsa version. At what RPM are you shifting with this cam?
