Holy crap they are some thick flanges for cat delete pipes!!

The problem isn't that it was a top mount, the problem is the size of the stock blower and the boost you were trying to hit with it. Compressing anything produces heat and spinning the tiny blower much past stock speeds just turns it into a heat generator. Any larger blower will produce the same boost but with lower temps, its just physics.

Now for your power goals, yeah, you absolutely needed to go PC or TT

I used a 15% lower pulley. 2" Kooks headers with Cat deletes. Roto fab Cai. and tune.. Was a gain of about 100Hp. Its stupid loud with the Deletes .But a riot to drive !! 662.40 rwhp 624.99 rwtq vs stock 577.94 rwhp 555.21 rwtq

that's true. haha. I love the Whip, but even for me, i would of pushed it to the limit creating more heat so what was the point. I almost ordered the Whip, but Matt was like, u ain't never gonna see 1000 plus without heat issues so.



On the stock lt4, if I had it to do over again, i would of just not done anything to it. haha. and went straight balls out.

Here is just doing the lower.. I've dynoed at Sorians place 643, 658 and 659.. I'll say its 650 rwhp.. I did it all for less than 2100.00 including the tune... Shops price 4500 plus!

I think the lower is easier to do yourself vs taking the snout off and pressing the pulley off, there was a guy that cut stock one off a few weeks ago and only had marginal scars on the shaft. Nothing terrible.. Another thing about the doing the lower it's not wasting 230 plus if you get a bigger blower later.

I see a problem unless you have unlimited funds like Scott lol! I'm Jelly! The next 100 hp will cost an arm and a leg and you will have to use meth to combat IATs and as fueling source...

You can spend money (parts w labor)on heat exchangers $1600.00, low side fuel pump $900, a cam $4000.00, an upper $500.00 even port the heads $3200.00 and port the blower 1800 including the 103mm, Flex sensor $600.00 but, the fuel system even with the cam will not let you run straight e85 its gonna be a 93 with e85.. and you will also need meth.. If you want to run all e85 and not play roulette using meth it will cost another 1500.00 for the lingenfelter pump and 3600 to 4500 for Hiflow injectors from Fic or Lingenfelter. meth or all e85 should squeak out 800 rwhp with the baby blower to me I think its total waste of time to sink that time and money into such a baby blower that will max out 800 not to mention it will not be very efficient.

I'd been down that path 3 builds ago I was never doing that again I try to do mods that can be used as the end goal making the dollar stretch further. Every thing I did will transfer if upgrade to a whipple or 2650 blower.. the lower ATI ring will be a snap to change boost any time.. 230 for a upper plus labor isn't that much i guess to waste but, the lower only seems to be just fine and its not over spinning the blower to terribly in the heat.

I cant wait till the Kaytec injector pump is ready for the ZL1 its out for the vettes it will be about 5k and bolt on running off a belt. Then I'll get the FIC injectors and be able to run straight E85 with a 2650 blower probably will not even mess with a cam. Those mods I can do easily myself and get it tuned I'll probably do spring upgrade, locks and trunnions as well.

just figured I through some of the cost out there in case your unaware..

I think a lot shops talk people into doing a cam which is about 1500.00 in parts and 2500 plus in labor and tune.. only to pick up about 50 hp (yes you can make more if you run meth or mix e85) but a lot of times shops don't tell ya that. to me its to risky to rely on meth as a fuel source.. unfortunately that's the cheapest way since DI is so expensive.

Thanks man! Saw your other post so I'm guessing you don't have it anymore. But what about these "belt slip" accusations what I've been reading about on here with doing the upper pulley?

That's what I was thinking! Just throwing on some cat delete pipes and calling it a day. Are those on your car yet?

If your builder doesn't know what he's doing, then he doesn't know what he's doing. Order the 2.30 metco upper pulley. Add the green HD belt. Call it a day. Get used to the power, if it gets stale over time, then start doing intake/headers. Eventually add a meth agent.



I got 803 hp out of the Lt4 blower, but it was a dead stick as I over spun it way too much creating insane amounts of heat soak. If you are just looking for some extra giddy up. You can go wrong doing either one. Upper or lower only. Put on a HD belt and tune. You good to go. Enjoy it.

Agreed. you don't really NEED a cam unless you plan on going on a bigger build. Yes, does it help? Of course. Is it the above all end all mod? No, not at the price that it cost and the returns it gives you.



If I had $4500 to start off with, I'd go upper pulley/headers/intake/tune/meth.

LTs are a waste on the Gen 6 unless you are going big and they ruin the sound IMO. And we already have shorties.

But what if we want to keep the forward cats to be a planet friendly person? Does anyone make a stock location high flow/heat cat for the ZL1/SS? Or would we have to build our own? I do not mind losing the rear cats, so that may help get some of the heat out faster.

I see some are getting nice gains out of the bigger TB (NW102 or ZR1)/ported SC/Rotofab and tune. (And maybe you can run this without a tune?).

The more I read, the more I am sure I do not want any pulley on this little SC. But if you can get 40+ out of that combo why not just do that? Your car looks stock.

I have a metco upper pulley, 2.3" that I would be willing to almost give away. I ended up buying the griptech 2.3" upper from weapon, and don't need them both

Is it real loud in normal and sport mode as well? Any drone, or just loud?

Since no one else has asked, who makes these? They appear to be rightfully proud to put "CA" on them.

[bobby35ny]

I wonder if there is any HP to be had by only using high flow front and rear high flow cats?
