How a 426 fuel injected hemi sounds with no exhaust
« on: June 15, 2007 - 10:31:01 AM »
Hey there,

I think NZ was wondering in another post how a fuel injected hemi would sound and if it was different from a carburetted engine.  Soooo, check out this link as I finally got the hemi dropped into the chally and in running mode.  It definitely has a raw sound without the exhaust :grinyes:  I drove around 100 miles from my dads to the exhaust shop like that.  Best headache I have ever had.  Enjoy!! :2thumbs:



ciao,
dray

Damn that sounds cool.  Sounds like the mic on your camcorder is going to blow lol.

Good call on the EFI.  I bet that thing runs @#$ing sweet.
I love my 440...but it's not loving me back...yet

Sounds good Dray, to be honest, hard to hear with the mic speaker playing up but you can definitely tell a big difference in idle. I asked Tim @ FHO and he said no note difference just idle if anything. Once underway and into the rpms no one would ever know accept maybe the driver because of the better throttle response. Sure sounds like it would be a perfect street engine. Can't wait to get mine going. I gave Tim the nod today so I should have the engine in NZ within 1-2 months, he said he's getting through plenty and well on track.

Thanks, have you got that other one you sent me in an email? Under hood one?
You should put that one on, that's much, much clearer with some revs too.

Hey G-Man,

As far as gas mileage, I haven't figured anything out yet, as I have been dealing with some leak problems <radiator, oil blowback through tapet covers, tranny leak, rear end leak and a gas tank leak  :roflsmiley:>  These full powertrain swaps need the a little tender care and attention to iron out the kinks.  Anyways, I haven't been driving the car much because everything is still fairly clean and I don't want to get oil all over everything.  Once I get all the leaks fixed, especially the gas tank one, I will give it a MPG test and post back to you with how it is running.  This might take a couple of weeks as I am a little bit worried about my tranny leak and need to get that fixed first.

Personally I would not go with the 6 speed in your build as the Hemi heads are particular beasts and while cruising anything below 2500rpm won't get enough oil pressure to stop premature value wear.

Hey NZ,

Gratz on the go ahead with your build.  It is definitely very exciting for me, specifically 3 different times. 1)When you get that crate marked hemi and first open it up  2)When we set the engine into the engine bay and 3)The first time it fired up.  You are going to be having some cool days ahead of you. 

A gotcha I ran into with the EFI was that the crank pulley <I went with the March serpentine kit> was 3/8" too thick due to the magnetic trigger that was set on the crank.  I had to get this machined to make my belts align correctly.  Just keep that in mind when you are deciding on what kind of belt/pulley system you are going to use.

As for another video, that must have been someone else as I have only made one video post of the Chally.

Cheers,
dray

Hey Dray,

Oh, OK....then who the hell was I emailing?  :clueless: :smilielol: It was a green 426 EFI car. It wasn't your car but you pulled the video clip from some website and emailed me it? May have been someone else then.

As far as belt pulley system, Tim is looking after everything. I want a stock looking engine so most parts will be black and hidden. He's doing the brackets, radiator, fuel pump, fuel tank set up, k-member, mounts, shaker set up. Basically set the engine up at his shop, dyno, tune, kinks, test then send it out to us ready to drop in basically. Of course we'll drop it in before paint to make sure it lines up and sits properly but apart from that should be a complete engine set up. All we'll be doing is hooking up the lines and cables. Can't wait, the first time I'll ever hear a Hemi, a big one at that lol. Must be a very exciting day. Do you have sound deadener in your car? I won't be as Lucy is too quiet for my tastes and I like to hear my engines. Lucy is nice but more of a classy cruiser, I want my 'Cuda to be a wild one with electric cutouts as well. lol If you have/n't go it what's your opinion on the in car noise? What exhaust are you using? tti 2-1/8" headers with ??
