jbc3 Posted March 13, 2007 Share Posted March 13, 2007 I just upgraded my LT-1 heads,cam and intake in my 280Z. Here is a little video of the car idling in the driveway. I think my days of sneaking up on anyone is probably gone Unfortunately the camera mic makes the motor sound like it is clattering, but I think it is picking up the header noise. Now I just need a little tuning time. http://videos.streetfire.net/video/4a862a58-3d0f-41d6-9758-98f000d404cd.htm Jody Quote Link to comment Share on other sites More sharing options...

Bartman Posted March 13, 2007 Share Posted March 13, 2007 Sounds nice and mean. I'm sure you'll be able to get even better times out of her now. Quote Link to comment Share on other sites More sharing options...

9t4ss Posted March 13, 2007 Share Posted March 13, 2007 That is so sweet sounding!!! Someday when my car grows up I want it to sound just like that!!! Alan Quote Link to comment Share on other sites More sharing options...
getZ Posted March 13, 2007 Share Posted March 13, 2007 You make all that power out of a single 2.5 inch exhaust or is that 3 inch? Quote Link to comment Share on other sites More sharing options...
jbc3 Posted March 13, 2007 Author Share Posted March 13, 2007 The seats are out of the 95 Z28 donor car. My exhaust is 2 1/2 out of the headers, thru 2 cats and then it combines to a 3" out the back. Yes I am running cats, I got sick of the exhaust smell. I figured I could afford to give up a few HP. I am thinking of making a 3" dual- out the side, open header pipe for the race track.

m1noel Posted March 13, 2007 Share Posted March 13, 2007 Jody, Love that little cam slop. Lope, lope. Sounds really good, I'd like to hear it rev a little. Mike Quote Link to comment Share on other sites More sharing options...
deja Posted March 13, 2007 Share Posted March 13, 2007 Very nice, as if that 10.629 wasn't fast enough, LOL. Can't wait to hear the new times. Quote Link to comment Share on other sites More sharing options...

Phantom Posted March 14, 2007 Share Posted March 14, 2007 Jody - really sounds sweet. Makes me want to get a better cam in mine. It's still stealthy at idle but really announces it's presence when stepped on. BTW - when I left Texas I took off the 280Z28 tags so you hold sole rights now.

BTW - when I left Texas I took off the 280Z28 tags so you hold sole rights now.Bill Even at idle, the car is significantly louder with this cam over the last one I had in, which was a GM 847 234/242-112. The new cam is a Bullet billet asemetrical lobe 25x/25x-108 with 612 lift. Last night doing a few test rides, my son easily heard it and I was close to a mile away. OK, maybe I was opening it up a little I tried to get 280z28 tags and the state said that the combination was too close to the issued combination, so it was denied.

heavy85 Posted March 14, 2007 Share Posted March 14, 2007 ... thru 2 cats and then it combines to a 3" out the back. Yes I am running cats, I got sick of the exhaust smell. I've thought about running cats for that very reason. What ones are you using? Thanks Cameron Quote Link to comment Share on other sites More sharing options...

jbc3 Posted March 14, 2007 Author Share Posted March 14, 2007 I am running a set of cats that came off of a friend's ZO6 Corvette. He pulled them off with about 2K miles. The price was right, the size was right and I saw little power loss. So far I am happy. Quote Link to comment Share on other sites More sharing options...
Phantom Posted March 15, 2007 Share Posted March 15, 2007 Do the cats act reduce the exhaust resonance inside the car? I've thought about putting a set on for that reason. Quote Link to comment Share on other sites More sharing options...
jbc3 Posted March 15, 2007 Author Share Posted March 15, 2007 Do the cats act reduce the exhaust resonance inside the car? I've thought about putting a set on for that reason. The car is still quite loud, but the resonance was reduced alot. I still have a 1800-1900 rpm spot that under certian load conditions is tough, but overall it is much better. Now I have never run real mufflers on the car. Before, I had 2 2 1/2" Dynomax mufflers along the sides of the transmission (where I have the cats now) then they Y together and another 3" Dynomax muffler out the back. When it was like that, it was harsh in the car most of the time. Quote Link to comment Share on other sites More sharing options...
Phantom Posted March 15, 2007 Share Posted March 15, 2007 I thought maybe so. My 280 is/was a California version so the L28 came with a catalytic converter. It seemed to act like a resonator and kept the car pretty quiet inside even when I replaced the original muffler with a more 'sporty' type. I'd also feel a bit better environmentally too if I had them. The problem now is the cost and if I can find a place to put them on the current system which is dual 2 1/2" through an X pipe to a dual inlet muffler in the rear.
