So I bit the bullet and bought a new test pig. I've needed something that I could try new designs on and make changes immediately and now all I have to do is steal this away from my wife to do so

My buddy JBroas will post up a pic since Photobucket is being stoopid LOL

Bam

baseline 1/8 mile times this Friday (as long as I don't have to break in the engine??) and baseline dyno numbers the following week:lol5:

 

[dirtydeeds]

haha, no, but he knew about it before my wife did. She thought I was going out to sell my Dodge. I just want a low key truck that can tow my gen1 to the desert and the wife can daily drive my kids to school......

 

[dirtydeeds]

DUUUUDDDEEE!!!

I needed make my way down there, and check it out!!

You really gotta come down here either way I'll buy pizza and beer. I got a guy chomping at the bit on me to make an adapter plate to use pacesetters on an 05-06 tundra. Can ya come down this weekend? I have gas money too$$$

 

[dirtydeeds]

Keith I will be down for the 4th of July - what kind of party you throwing

Lol. No parties I'm family guy, but we should meet up for some pizza or something!!

 

[dirtydeeds]

I am bringing the family too, so not that kind of party. Pizza one night sounds good. I will txt ya when it gets closer and see what's up.

I just installed a 6" system ill shoot and post pics tomorrow.

At Qualcomm stadium race legal 1/8 mile in 4HI I was consistently pulling 2.2 sec 60' and 9.6 sec E/T. So that's my baseline E/T. I can't wait to see baseline dyno numbers

 

[dirtydeeds]

Congrats! I got Jim's Voicemail this morning, learn to turn those nannies off! Haha. Hold the button for 3 seconds until you see lights come on, release and hold for another 3 and you're good!

Ya. It's crazy, I actually worked with a guy at Toyota corporate last night to figure out the nannies. I couldn't get em all off. I guess I gotta read the manual. My truck was different from his.

trying out my new photo hosting site, photobucket won't let me upload pics, so here's some pics from flickr.

less than 150miles on the odometer this truck wins a trophy at the drag races on friday night:lol5:

with the high demand for a race only cold air intake I will be testing that first. I can't wait til next Saturday:lol5: for some dyno time!!

 

[dirtydeeds]

The most tq I saw stock was 335, and with my 6" bolt on max was 337:lol5: It's not as much as I thought, but in the 2 minutes we went over the graphs it looks like tq comes on a little sooner. I'm waiting very patiently for the dyno sheets to be emailed to me!! printer was down

so 319HP and 335TQ is my official baseline. Videos and dyno sheets to come asap.

I cant wait to see what the mid pipes do. Im looking into a similar setup with keiths expertise and getting my supercharged DC 4x4 on the dyno as well.
Im guessing all gains will be multiplied on a supercharged truck, but we will have to wait and see

I know!! I can't wait to build these. I'm building the front nipples/flanges tonight and the dual 12" mufflers that I intend to use to keep the sound reasonable tonight as well.

My feelings are mixed on the results that I'll see. I've always taken the stand that there is little to be gained by removing the cats if you still have the stock manifolds. I could be wrong.

One thing that is pretty common on supercharged trucks is that the cats blow out. So this will make it very cost efficient to fix that for sure.

All testing will be done off road in the desert then the truck will be returned to stock before driving on a public road way. These pipes are only for use on a vehicle that is not driven on public roadways.

And I agree, any gains on a naturally aspirated truck will be compounded by a supercharged truck. Here's a teaser:

I'm very interested in your result. As we discussed on the phone, I'm on the fence between getting new cats or doing the multiple mufflers.

We will talk again!

refresh my memory, were your cats on their way out? these are an off road only application

 

[dirtydeeds]

Ouch, I thought I was special


Just kidding lol

I have no idea, but I know the exhaust sucks. I want to keep it very quiet though and I need to keep the stock manifolds till my extended warranty is up.

We discussed making a b-pipe with 4 mufflers and the cat back with 2 14" mufflers. I might still just order some pipe and some J-bends and tig up something. I can't spend any money till we close on this new house.

that's what she said:lol5: and I assured her that she was LOL

ya, the pipe has hidden pipe inside it

And here's what I've built to fix that, off road use only, not intended for use on any vehicle driven on public streets.

 

[dirtydeeds]

Here's the first step to ridding these trucks of their hidden bottleneck;

I'll bolt these flanges/nipples to the stock manifolds and build the rest of the pipes using all mandrel bent 2.5" tubing.

 

[dirtydeeds]

Wait, wait, wait, wait!!!!!!!!!!!!!!!!!!!! Keith..... are you gonna start making CAI's for our trucks?

haha, yessir, I keep pushing back the prototyping tho. Race only, not for use on any vehicle which is driven on a public roadway.

so I tested the off road pipes on the dyno over the weekend. it drove me crazy how loud it was. it sounded like a machine gun whenever you step on the throttle LOL. And it blew out a lot of low end. However, top end screamed and it added 7hp on the with 15lbs tq to boot:lol5:

So the catless mid pipes are done and ready for production but I don't reckon I'll be selling a lot of em with the relatively small gains and low end tq loss. They would be perfect for guys with blown out cats, and of course guys with superchargers that want all out performance and wanna keep their warranty so they can't remove the stock manifolds. These are of course only for off road use on vehicles which will never be driven on public roadways.
