Well I got the Maggie 122 finally installed over the weekend. I was really anxious to get the tuning started to see how the LS9 ZR1 cam would respond. All I have to say is WOW!!!!. I haven't done a dyno yet, but I've been logging and tuning all weekend and so far it's amazing. I'm having Steve Williams of tunedbyfrost and LSxtuning do my tune. He has done an amazing job so far. He is doing a MAF tune and we've almost got the MAF maxed out (not sure what specs are maxed). He's been able to get a ton of power out of this setup. I'm getting 8-9psi out of the setup so far on a 2.8 pulley. We spent all day logging and emailing back and forth and so far every little change he makes is making a nice difference in performance. We did an estimated guess on the rwhp with the injector duty cycle and a few other specs and we came up with about 538 rwhp. From the other setups we compared the calculation to, they all came out really close to the actually dyno numbers. It is still running very rich up past 4k rpms so I think we will be able to pull some more out of it before its all said and done. I'm hoping to dyno it this weekend and see what numbers it's actually putting down.

I think the only thing really holding my motor back is the heads. When I get some more money that will probably be my next purchase.

Nice. How's that cam sound? Like stock?

 

Sounds almost exactly like stock. There is a very very slight hint of a lope, Nothing you would notice unless you are trying to.

 

how far are out able to pull the motor, 6-6.5k?

 

videos????

 

added videos

 

how do you like the blower setup compared to your 427 stroker setup?

 

I like the Magnacharger way better. The power is about the same, but I'm getting about 12mpg better with this setup...

 

definitely a sleeper setup

in the vids is sounds like you just did some exhaust work.

 

+1, tell everyone that the whine is your water pump going bad

 

Nice, just saw this..

Glad that you are happy with the way the car is running.

 

What size pushrods did you use with this cam?

ThanX

 

I just used stock length 7.4

 

i thought these cams had a smaller base circle?!

 

dyno numbers?

 

Pretty cool.

Can an intercooler help a Maggie................

.

 

That's insane, I should have done this with my LQ4 in retrospect, looks like you've got plenty of passing power!

 

Very nice set-up!

 

bump for an answer

 

did you check the pushrod length when installing or setting them up?
any dyno numbers?
