To be honest the only performance gains are in the headers and cats. The factory mufflers are not restrictive.

If you see my dyno sheets, with everything stock we were at about 560 rwhp on a dynojet. Once I added headers and CAI we were up to about 590 rwhp. So about a 30hp gain. Does this give you an idea of the difference?

94guy,

What other mods are you doing? Are you doing headers as well? Hold on and we will get you a better answer. The more I think about it, the 3.875 pulley may give you too much with no other mods. I'm at 8psi peaking up to 10 at very high rpm. We will see how we're doing after final tuning.

When you get a chance, could you please give us a pic where the meth injection is taking place?
Thanks!

I will make sure Tim posts pictures of the install. He is away for Labor Day Weekend, so nothing until probably Wednesday. Tank is being shipped.

The pump is mounted low in front of the factory windshield washer reservoir.

WOW....you guys are putting together the perfect gen V. MAD props to you! I really have to wonder why you're fooling with a meth system though. I know the myriad benefits, but dang....don't you, at some point, try to symplify things a bit? At some point along the journey, don't you really want to just drive the snot out of that thing without having to worry about whether your meth system is kicking in at just the right time (or how much meth is in the tank....or if the system is even working properly)? If you tune it to just make everything "safe", there's no reason to fool with it in my book. Everything else about this build is being analyzed to hell and back. Just wanting your thoughts. Your Camaro will most likely run a little better than my wife's (gen I, carbed 406 with turbo 350 tranny). I admire you for taking the time to share. I wish we were a little closer. I'd love to take a ride in that thing

The tune will be a safe one so that if the system ever malfunctions I will not put my motor at risk. I figure if it adds a degree of safety and some performance than it is worth it. At this point, it is debatable if it is needed. In the future, when I can afford it, I intend to build the motor and increase the boost. Then it will definitely be needed.

The system really isn't that complicated and has been used for years. There are many reputable shops and forum members that swear by it. I'll try it. If it becomes an issue, I'll remove it.

I`m pretty sure he has a similar setup to mine. ARH 1 7/8 longtubes, high flow catted x-pipe, I think he has stock mufflers. He also has a CAI I can`t remember which one. So I think he will possibly see a small boost drop but maybe not. you guys did not see one on yours but of course that goes against conventional wisdon w/ the exhaust being changed. Only thing I can think is the CAI balanced it out somehow, being more free flowing.

I can`t remember, which CAI are you using on your setup? I know you guys tried several. Did the car idle properly after the CAI install? Whipple seems to think it won`t run right w/ a CAI until you custom tune it. I think thats because they are so used to the Ford aftermarket CAI guys adding the larger diameter intake tubing on CAI`s throwing the MAF off. Our GM`s already have large tubing and larger tubing is not needed on most builds. So if the intake tubing diameter at the MAF is the same size as stock then In my opinion and a certain other shop owners opinion it should run fine at idle and part throttle w/ Whipple`s canned tune. I don`t beleive Whipple has even tried any CAI w/ their kit and are just trying to be safe. But maybe you could ask Tim to see if he had and drivabilty issues, w/ idle and part throttle driving? If so I would appreceate it. I want to be able to drive the car to the dyno after I install everything for the custom tune. Of course no WOT runs...Lol..

Another caveat to this that may help you or others is what a buddy of mine experienced on his 4th gen build. A little background on the car, its a NA setup built 402 stepped headers and true dual 2.5 inch exhaust no cats that was custom fabricated. He put down 523rwhp to the tire thru the exhaust. He added cutouts and with them open it put down 561rwhp. So seeing as how we are in that power range w/ this kit 550-650rwhp depending on setup it would seem to me the 2.5 inch axlebacks are going to become a restriction. Thats why I recently added the Magnaflow 3 inch catback. I already had the ARH 1 7/8 headers and high flow catted x-pipe. However, I did not use the magnaflow x-pipe and tied the connection pipes into my ARH 3 inch x-pipe. It can be had for around 900 bucks, lot of specials running on it. Just food for thought.

I agree with old motorhead. I have seen two over 1000hp Camaros, several 850hp Camaros and CTS-V's, and more than I can remember blown 800hp cars here in DFW area built by ADM Perf. Guess what, NO METH and safe tunes. Some factory stock motors and others built. The KISS philosophy is what "old motorhead" and I agree on. Keep It Simple. On this Whipple build at this time the meth is overkill for now. However, I really like what is going down on this build in EVERY other way excluding the meth.

[Roto-fab 1]

Can you post some pics of the Roto-fab CAI installed with the Whipple? We typically gain about 35HP with Maggie equipped cars, so I am curious what just the intake would have done over stock for this application. It doesn't sound like we will find out on this particular car though!

You guys make a valid point and i agree that METH is NOT nessesary for this build.
But i also agree that a new clutch or new axels is NOT nessesary.
But they would have benefits. Kind of like the METH kit.
i personally see the benefits as a no brainer, and a useful mod.
weather or not its NEEDED is besides the point.
Headers and CAI are not needed, but no one is complaining...

Great job on the build journal, keep the info comming!

true meth is not needed for this build, but those 1000hp cars that arent using meth, what octaiin are they using? i highly doubt its pump gas. i'm sure its atleast like e85 or 100+ octain race gas. just hard to c 800+whp using only 91/93 octain. but thats just me.

personally i like the fact of using Meth, not the drug lol. it has so many benefits. so u have to check it regularly, eh its part of regular maintenance imo. just like checking ur oil, coolant, tire pressure, blinker fluid, and ever so pesky muffler bearings.

Mufflers bearings...sheeezee. Anyone and everyone knows that you can eliminate the possiblility of muff bearing failure by installing the inverse propensity hootis modulating regurgitator. Some people should just back away from the keyboard. Totally worthless use of my time to even reply to this........but I felt the need to set things straight, hopefully saving someone from making an expensive mistake...
