Been a while since these pulls were made, but figured I'd throw this up here in case anyone else wants to see what kind of numbers it can make.

All modifications can be seen in the sig.

Three pulls were done - first was 420, then 425 and finally 430 rwhp. Tuner thought there might be a tad left in it (90+ degrees, high N. Alabama humidity in June), but I chose to keep it safe. I was satisfied for the money invested and given that the weather conditions were so poor for dynoing. Also had just driven the car 100+ miles to the dyno....I rolled up and we just strapped her down and started pulling.

 

Good results bro!! Enjoy that thing!!

Thanks Jason, I have definitely been enjoying it.

Also have to say thanks to the TSP crew for being so willing to help with the questions and parts!!

I'm sure I'll be spending more money with you guys in the future.

Thanks!

 

I was about to say it looked low but then I noticed you have mac headers. Thats some nice power. How's it drive?

Nate

 

Good power out past 5000... Bit soft below 4500, but depends what you (the user) was looking for.

 

Nate, it drives pretty good actually. I was a bit worried about it when I decided on that cam, but once you get used to it, it's not that bad. No surge while cruising and holds an idle just fine. I will admit that I did give up some down low, but the hit up top made up for it. I imagine next time I change cams though, I'll make more of an effort to "maximize the area under the curve"!

I was originally shoot for 425-450rwhp, so I'll say I'm happy with what it made.

I've actually be thinking of swapping the Mac's for a set of 1 3/4 Kooks, but haven't made up my mind just yet. Those things are pricey!!

 

Yeah it turned out alright. Next time I think I'll try to get more under the curve though.

 

Was the cam degree'd? I've thought about this cam highly but am worried that it won't leave much more than ms3/ms4 would under the curve. I don't plan on spinning the motor past 6300-6500.

 

Oh I have that cam, just wondering what the heads did to drivability as well. I make 420/395 corrected cam only/bolt ons. Ditch those mac mids and get some QTP's with the HVMC setup for the same price of the Kooks.

Nate

 

Nice numbers man!

 

Nah man, I installed it straight up. From what I've heard/read, you'll see a better top end with the MS3 or MS4, but you'll more than likely sacrifice the low end.

I think GMHTP did a great article on the TSP CNC'ed LS6 heads and MS4 in this month's copy. I don't remember the numbers exactly, but they were good.

 

Ah, I didn't realize that...I guess you're pretty familiar with it then!!

Those numbers are real good. With heads it would be impressive indeed.

I haven't decided what I'll do just yet. Got to come up with the cash either way. That's always the tough part!

 

Could get a set of pacesetters and even throw in a nitrous kit for the price of the qtps or kooks. Like your sig says a well thought out combination . 550rwhp / some high $$ namebrand headers, damnit can't decide ...

 

Yeah man, I know what you're saying. I haven't decided which way I'll go just yet.

Right now, my checkbook is telling me that what I have now is what I'm stuck with!! Cause I'm broke!

 

im hopin my 233-239 AFR205 combo will hit close to the 460+ after my 90/90 combo and all bolt ons

 

Let me know how those 205s work out. I've been thinking about looking into those.

I'd like to see what numbers come out of that combo.

 

Marv I think you'll find you can make 460rwhp with a ported Fast 90 intake also.

 

Yeah man, I've been thinking of picking one of those up. Just need to find the funds!!

I would like to go with that and possibly a PTM or NW 90 TB. Also, might ditch the MAC mids and go with a Kooks setup (1 3/4 SS headers and 3" SS ORY). That should help the motor breath quite a bit.

Got a smoking isssue to resolve before I do much more though. Ever since I put the LS6 CNC'ed heads on the car, it's started consuming oil. My first hunch is that the rocker bolt holes that got ported into, aren't sealed up properly. I plan on pulling the rockers and resealing them. You guys don't think I could have possibly got a hold of a set with the cracked rocker mounts do you?

I highly doubt this, but I guess anything is possible. They were bought back in May if that helps.

 

No I seriously doubt it. I bet you just have a rocker bolt not sealing properly. Keep in mind those things are brand new GM guides so the odds of them consuming oil is pretty slim to none... Call me when you get ready for a fast 90 & PTM TB, I'll take good care of you!

 

good to see another using this setup.

you can check my sig for my dyno thread and other details if you wanna compare combos. I say you need some headers bad.
