Here's a before & after from a recent MS4 camshaft swap into a 02 Corvette! The car received a MS4 camshaft & a underdrive pulley!
The car has a blackwing induction & TSP Long Tube Headers Before the cam swap!

The specs are : 239/242 .649"/.610" 111

 

Nice #'s, that is a big cam...you need some head work to let that thing breathe.

 

Hey Jason is that the Red Z06 we saw up there yesterday? Awesome numbers! Thx for the tune, this thing is such a blast to drive! I'll be talkin to you guys in January about some heads to throw on.

 

Impressive numbers Jason & i'd like to know the exact PTV clearance on LS6 Heads with MS4 esp. the intake valve ?!

peace

 

I want that cam!!! Another awesome job done TSP!

 

Nice final numbers.
Looks like the numbers before the cam were stopped too early. May have made closer to 375-380 before the cam and pulley.

 

Nice short power curve! Congrats!

 

Hey just spoke to Zach about the ms4?
Awesome #'s and very nice torque.


Was flycutting needed with the stock heads?




Zee

 

No flycutting required with the MS4 and stock heads.

 

Nice job! i wish to see thats cam with the TFS heads on the dyno soon ...

Thanks.

 

I emailed about question to one of your sales guys but never got a response. Anyways, how much do you guys charge for the ms4+stage 2 ls6 heads package? Also do you guys port the fast intakes. Difinately going to be a future customer.

 

Is this cam kinda doggy on the bottom?

I to would like to see it with the new TFs and a 90 setup.

 

How about with the new trickflow heads? I beleive this combo would be KILLER!!

 

I cruise in 6th at 1400 rpms with a 3.42 rear in my M6 C5 with no problems at all.

 

am i reading the graph right? are you shifting the cam at 6500rpms? i think i found my PERFECT cam...now i needs monies

 

Looks like a few more rpms would have shown a few more Hp. Did you upgrade to comp 921 springs or an equivalent? I am willing to bet you would've hit 445 or 450 rwhp CAM ONLY had you spun her to 7000 rpms. On the other hand if you never spin her to 7000 rpms then what does it matter, right ?? 6500 is enough and AWESOME numbers with a cam only setup. The MS4 seems like a monster. Let us know how you do with a set of heads. Probably another 40-50 rwhp waiting depending on what heads you get. Hell 440 to wheels is enough, leave the stock heads on and go kick some ***.

 

I think this is the main reason for TSP to designed these kinds of camshafts

PS. With MS3 alone on stock heads we gained 80rwhp & it's time for heads

peace

 

They are the new PRC HD Dual Spring Kit designed for the more aggressive lobes. The cam works great with stock heads, but will shine even more with some heads. I believe he will be coming back in for some Stage 1's, I can't wait to see what it will do after the heads!!

 

Thanks for informing me on the springs. I knew it had to be something good to handle that big lift/duration cam. Out of curiosity what do you think would've happened had you pushed the dyno run to 7,000 rpms. Another 5-10 rwhp? Reason I ask is that the graph appears to be on a continuous climb. Sounds like a little more air flow with an aftermarket set of heads will allow even more power to be made. I'd guess 480 rwhp +

 

Another 5-12 could be seen if spun to 7k I bet, we'll see what happens with the LS6 Stage 1 head setup, it should be good!
