After K&N cold intake, Granatelli MAF sensor, & Granatelli power tune - now it doesnt only sound mean, it is mean.

Thanks for the info looks like a nice exhaust system. Is there a lot of drone in the cabin? or is it pretty mellow at crusing? Also is the Granitelli tune similar to superchips or hypertech? I was looking at the Zoomers exhaust because it's a true dual system with an X-pipe. I heard them at my dealer and I really liked the sound. Has anybody got this set-up?

I may pull the trigger this weekend it really looks like a well built system really different than anything else out there.

Granatelli very similar to hypertech.......they are handheld tuners.

As for cabin noise......more noise from the K&N cold air intake than the exhaust. Doesn't seem loud in the cabin at all. The design is meant to throw noise out the back. I had a friend run down the street for to here the way it sounded. Much louder on the outside than I expected. Considering how it sounds from in the rig.

Thanks for your help on this guys, I think I'm going to get the Zoomers cat-back and the Hypertech tuner. I'll let you know how it comes out.. Zoomers says they can do both for me install the exhaust and run thru the tuner procedure. They seem like nice guys over there and can take me tomorrow for the installation. I was going to try it myself but for $100.00 bucks for both it's not worth killing myself...Bad Back! $999.00 for the exhaust and $339.00 for the tuner, seems like a good deal...

Here's my review: http://www.elcovaforums.com/forums/s...498#post361498

If the K&N is loud which is what i use to run, wait till you hook a supercharger to any cold air intake. It get's real noisy at WOT so turn the music up loud unless using factory intake not so bad. Then again it takes the fun out of it because the people in lane next to you hear it too.

It is the coolest sound you can here. I cannot imagine what it will sound like at 20 lbs. of boost versus 10 lbs.. Dragon and I run a custom made cold air intake we redesigned to fit engine compartment which will change when we do away with the MAF completely and try to fit methanol inj. and co2 tanks under hood. We are running out of room so I'm looking at mounting a high flow air filter right on throttle body so that is one reason we went to reverse cowl hood so it would suck co2 spray out quickly as if it goes in air intake it will choke engine down. So another adaptation to hood maybe a vain catching air from radiator up and over engine which would catch heat from radiator and take it out. This is a good thing but, have a second vain farther back behind the throttle body to take engine heat out the hood which is another good thing but, I'm thinking not needed once we feed co2 spray past throttle body. This would allow colder air to intake if filter has to be mounted to throttle body but, most likely we can bend a tube to go over into or near right front of engine bay away from co2. the the vains would not be need but, sounds to cool to not do though. Well ideas are what makes the world go round now a days. It got us to the moon at least. LOL

So a few details to work out yet with placement of things. co2 tanks i'm thinking twin chromed mounted in back with all the high tech sound equipment, one on each side. I like to keep a balanced look easy to reach to refill and use chrome braided tubing to run up front. The only thing not needed to make is the hoop to hang in front of SC aftercooler as a few companies make them already but for nitrous use on air to air which nitrous is to cold for water aftercooler nitrous will freeze the lines. That should leave room for one tank under hood for methanol inj. tank. It needs to be closer being gravity feed not pressurized like co2 tanks. I have come up with idea of using nitrous bottles for co2 and making a screw on top for meth inj. tank since it is not under pressure just plumbed for flow out and then bypass if engine is not using all it is getting like fuel inj. just allot simpler. Just micro switchs on throttle body to open valves at WOT or can be set for earlier if wanted to help with less pedal as far as meth.inj. is concerned. You just have to have a stored tune that you can switch to for earlier inj. spray with less fuel.

Well love this stuff and say to many sorry guys and gals. But, just hope I pass stuff along that helps somebody and at least it can be found in a search of archives. But, I really hope if anyone reads what i'm discussing and has other ideas they will share them with me. I love to learn and many many know more than i do about all this stuff. I'm self taught from reading, studying tuning maps from sponsor as well as only one maybe 2 other tuners aroud here i would trust, what Dragon knows which is allot, Allen Nelson and some other really good setup guys. So please anyone that has even read something that is interesting let me know about it. There are new concepts coming out all the time. Just not many people look at the H2 like i do and what they have will not work because of the weight factor but, sometimes i can adjust the concept. So really anyone jump in with ideas. My Grandad told me the only stupid question is the one you do not ask so i'm asking for any ideas or thoughts. I know some of you guys on here are scientists maybe rocket scientists. We'll strap a rocket to the butt of the thing if it will get me good times at the trap runs late this year.
Thanks for all of your patients. Many know the serious struggles i have fought in my life last 3 years especially health wise and i think about the people who have always keep check on me all the time and count the forum as the long lost cousin but, still family I just have not gotten a big money handout because the cousin is filthy rich. Well money is not everything it just keeps the lights, water, gas, food, kids in college, and well you get the idea. LOL
