Just installed the mp112. Got a hell of a deal couldn't resist.

Have 1-3/4 kooks, no cats, magnaflow catback. K&N cold air, AEM water meth. 2.8" pulley. Have a vrx4 cam in it.

I know I need a custom blower cam. But I needed it to get tuned anyway to run.

I made 380rwhp without blower. After tuning with blower I only made 440rwhp with 24* of timing.

I'm seeing guys running 500 atleast. Are my numbers low? I don't think not having a custom blower cam would hold me back that much hp? Just seems low to me .

Any input would be nice. Time for new tuner? Or is my motor ****?

if it made 380 your motor is healthy. How much boost?

bubbolootz

7lbs I believe

Try the lpe gt9 cam, and drop ur timing. Its too high for boosted application.

You should be around 14-17 degrees of timing. More boost less timing

bubbolootz

The more timing we threw it at the more power it made. No knock. Only thing I can do is 2.6 pulley and O.D. crank.

24* is too high for stock compression. You're going to break a ring land. I would not go over 18* on the stock short block.

On power, you may pick up a few hp by replacing the valve springs now that you're boosted. You can go with a small cam but I wouldn't go crazy, the Maggie won't support much. A cam that favors the exhaust will really help, 218/230 ish duration, lift below .600", and 113-114 LSA.

Your numbers aren't too bad, honestly. Don't waste the money for an LS2 throttle body, there is no power increase from it despite what you may hear (real world 3 whp at most).

Have dual springs and hardened pushrods, milling oil pump. Did all the needs for the cam when installed. I'm glad you told me that because I was going to do the ls2 snout and tb atleast 600$. So obviously it isn't worth it. Guy at the dyno said get 115-116 LSA.

On lower timing we weren't making much power. Whys that.

380 seems about 20-30rwhp low to me n/a, throwing boost at it may very well have caused more issues. The cam isnt holding you back, I have seen a maggied car with a magic stick 3 make more then 440. You might be getting away with more timing because of the meth. I would try replacing the plugs and doing a tune without the meth and see what it does.

Admittedly though since you can do it for free, rent a compression tester from a parts store and while youre changing plugs check each cylinder so you know from there on out if you have a bottom end problem or not.

Does seem low for the mods.. Engine I'll bet will check out fine.. Might just be the combo u have. If it didn't knock with 7lbs and 24 degrees then I would pull back timing and add boost.. See what happens

bubbolootz

Already have a compression tester was going to test it come winter, plugs might have 20,000km on them if that.

bubbolootz

Can only run so much boost with these blowers there pretty small. And without the meth it would heat soak like crazy.

I made 453 on a dynojet with a 112, 1 3/4 headers and 90mm tb and snout on my LS6 with stock cam. Timing was around 18 if I recall correctly.

EDIT: boost at ~7 psi

barrok69

I'm at 476whp with 9psi (2.7" pulley) 1 7/8" kooks and catted corsa. I'm running V2 iridium Delco plugs. Stock LS6 motor.

Your numbers don't seem that far off for the boost you're making.

Get a smaller pulley and drop your timing and you should see a ~20hp gain.

WEEEEEAK.

for the 5-6k spent on a blower alone that is so weak.

It makes me wanna give mine up and just hop on the V2 wagon.

I was thinking heads, blowe, and cam. but with these kind of numbers 8-9 k seems better spent toward a V2.

There are better blowers out there now. Someone just did a edlebrock 2300tvs on their car, that will be able to see some high numbers. Someone has a Whipple 2.9, hell that thing could support 800hp. I want to do a Kenne Bell LC2.6 on mine. See if that works at all. But I'll probably end up with the edlebrock. The Maggie 112 is tiny and its like 15 year old tech. Maggie makes a lot better products now also. Not much of what I suggested is bolt on or easy. But stuff that's easy, usually isn't worth the time.

That engine needs a bigger blower. A 112 is ok for a 4.8 or 5.3 fir towing. It's junk on a ls6.

ryridesmotox

10 years ago when 450whp was a lot, this blower was awesome. Now there are 4 bangers that make that much with a tune and bolt ons.

I don't even know what's considered fast anymore... 700??? 800?? 1000??? I can remember, 10 years ago, there wasn't 1000whp+ cars getting driven on the street much at all. Now, hell they are everywhere.

bubbolootz

Paid next to nothing for it. Was brand new. Car is also a daily driver not a weekend punisher. Sure if it was one day I week id throw a whipple on it triple the price...then blow the bottom end. 500 is plenty for the street for me.

I made 504/530 with a 113 over driven to 13psi. I just swapped a 122 head unit on but haven't had much motivation lately as I work too much. But just a couple stabs on the pedal shows 18psi. Lol

Still have a twin disc and fuel to put in and I'll tune it and see what it can do. Maggie's are great street set ups mainly for the fun factor and instant torque

You're right, yank it & sell it to me for +$5 . . .
