NOS will work and Holley says so, and they state no additional mods needed , And they have a kit specific for LD8 N*, (Dont listen to anyone without getting facts there is so much speculative BULLSH*T out there) It is used all the time out west where the sand buggies run. Alot of them N*'* Its a fad with them . still waitng for my kit. Ya. http://www.holley.com/categories.asp?division=NOS
got mine fer $569
I got the idea to nitrous because alot of sand buggies out west use it on their N* engines(alot of sand buggie builders use the N* One of the Major N* builders out there Cadillac Hot Rod Fabricators leaves the stock bottom end alone till they reach 400Hp...so keep that in mind....they build them from 360Hp up to 800Hp with whipple supercharger. I'm putting single jet on at first...75Hp and then 100...Thats as far as I'll go...considering the 4ooHp stated by CHRF for OEM bottom end durability. They have some info on N*'* and some eye candy on site but dont bother trying to contact them they work closely with gm/caddy div and are tight lipped AND wont sell parts to gm car owners, only custom sand buggy and showcar Manufactures. Period . But a few good facts, pics, info.
NOS is fine with stock every thing to 100Hp....and dont expect any chip work or mods to come out yet they just arent available ....and I've tried everywhere, but chin up
The 275Hp LD8 is alive and well over in the Buick division which is useing in the Lucerne , which by the way IS the new Bonniville. HEY which of ya Bonnie gear heads thru that brick...It'* true oo it'* true.
But seriously, Pontiac lost their *** on Bonnie in '04 and '05 and dropped the line for 1 year and put the cost of devoloping mid luxury full size sedan in the more profitable Buick divisions hands and IT will be back in '07 as the Pontiac G8 with the N* 275hp.
Seems like everyone is going to the jap/euro trend for letter number combo'*.
Maybe they will make a gxp version and bring back the Bonnie name (that ones wishful speculation) the rest I've read on net from reliable sources. ( But CHECK out anything ya hear ,even I make mistakes and 5 of them only call when they want money)(yuck yuck)What they have done to the Bonnie over the years. It left the markey once and came back as the butt ugly Parisiene and even made it a compact car at one time.
When I get NOS kit on and get a ton of pics taken I'll do a post on it and some pros and cons. AND there are some things to consider...like in an urban setting if you back off the throttle before the injection clears the exhaust ports , you could blow the intake right thru the hood and gas vapor/nitrous is almost as volatile and explosive as nitromethane.....Dont be scared (hehehe) and let the NOS force be with you
Because untill the 275Hp is used in some more models...and it is and will be THERE ARE NO mods for it and it'* been Talked to Death for 2 and a half years. I guess there * a cold air kit from K&N but its a waste of your time and money. The OEM airbox is used for much bigger applications than the 275 Hp and any Hp claims in my view BS. I f you were boosting ya maybe some Hp. But NOS doesnt need more air it supplys it'* own when the tempeture inside the cylinder exeeds 560 degrees on it'* way to firing the nitrous molecules split and gives you much higher cylinder compression and twice the Ox2 found in air. And the nitrogen passes as such with the exhaust. Holley states this gas has a cushioning effect on exhaust valves. Still looking for someone to bore throttle body and trying to figure out if heads can accept the STS OEM Exhaust vaves. I feel thats how they detuned the engine from 300 HP( my view not fact) Speaking of facts there is some info here and other forums and in each I've found errors so check anything you read out and dont do anything "cause someone said so and that surely even mean me ! Call Holley/NOS or email them and they will hook ya up with a distibuter near you.
