Try set of high flow cats.... don’t know why the m6 just runs better at part throttle with primary cats... but it does. I have large cam and it Runs way better with cats... way better.

Supposedly forced induction drops the rpm where peak hp is made about 400 rpm, with a centri, we can see that it can be pulled to provide super nice top end power and there is less torque so it is easier on the drivetrain.

That's all in the tune, your tuner should be able to completely get rid of it and if they can't you should look for another one. Maybe let Brett at Pray Performance do a remote tune, mine was almost perfect from him.

I am sure further tuning will help but I would never expect a cam with a decent amount of positive overlap to drive like stock. There is no free lunch...as you shift the power curve to the right, something has to give, and that is normally drive-ability down low. Loss of torque from dynamic compression bleeding off causes the low speed drivability issues. That is why it's a good idea to raise compression when doing Heads/cam setups. The good news is the VVT3 only has about 5 degrees of overlap, so most of that should be able to be tuned out.

Sounds good man, nice to hear something at that level NA is still streetable.

I'm a believer that not only are the centris lower torque a little easier on the drivetrain, they're also a little more forgiving on the stress they put on the rods. Seems most of the higher hp SBE cars that aren't blowing up lt1s are centri.

with cat my car is 100% streetable. At 45mph, parth throttle it sounds and functions like stock. WOT well that is another story...

Thats the plan. If my guy can't do it, then Ill be giving Pray a call.

thanks ted

all that power and the na guys are nearly as fast. maybe even faster now? oh well. It is all for fun.

That’s it Parish? Can you quit goofing off and make some serious power already?

The type of the FI used has little influence on the longevity of the engine. You can make a PD blower hit softer by pulling timing in specific areas of the timing map.

The fast NA stuff is much lighter. If you were 3400lb race weight I doubt anything NA would be close.

My excuse is not enough track time and average local tracks. Maybe this year I will sort it out.
