Well in that case more power to yeah... throw a 200 shot at it too then.

I didn't read the whole thread... wasn't trying to be critical. Just didn't want you to scatter it if it was your pride ans joy.

I always wanted to get a 496 vortec junk yard motor and spray a 2 stage 400 shot at it.

yeah its all good, its not something i care a whole lot about, now the real engine for the car thats a different story.

75 shot of nitrous is prolly as far as im willing to push it, i know marty with the black transam thats linked to in this thread was hitting his with 100 shot and i think at one time he hit it with 125 or 150 and it didnt hurt it but im not that brave lol

But if something goes wrong it could smoke that engine faster than you can let your foot off the gas under full boost. If its not for spool up then i cant see it doing any real good that a good intercooler and meth injection wont accomplish with less risk to your setup. Also you cant really over size the intercooler you can buy a big one for you next engine and run it on this one.

if you want to hit the 9 second range you will have lots of suspension work to do to get the car off the line and down the track straight. Better tires and lighter wheels will make your car faster than 75 shot when your trying to hit the low 9 high 8 second range. Now if you had said a 200/400 shot well then i would say "Spray Away". I have actually never seen a two stage kit setup to run in that low a flow settings. most are direct manifold and have bigger jets 2 kits hooked to gether and you got twice the chance of failure.
ive already got a massive 32x12x4 air to air inter cooler the nitrous will act bigger then a 75 shot always does on a blown motor due to the extra cooling, meth injection is only there to make this live on pump gas as the n20 will have better cooling properties then the meth.

its not a real 2 stage kit, its basically 2 single nozzle wet nozzles with my ecm controlling each 25/35 hp jet in one nozzle and 75/100 in the second nozzle i do have a few safteys in place afr monitoring built into the ecm,fp saftey switch and same with oil presure. wont rely on afr monitoring though as at full boost + n2o and some rpm afr readings will lag behind slightly so ill slowly step up the nitrous


i think it will be hard to get low 9's with out the added hp from the nitrous shot at this altitude

suspension is handled in the rear of the car not to keen on switching to 90/10 front struts and drag springs in the front just yet its still a street car that gets driven around alot

only thing im changing for sure suspension wise is the bolt/wled in fram connectors are comming out and im going with a threw the floor setup with inner and outter connectors as im already getting the dreaded cracks in the roof behind the windows

Your car i would start with a powerstroke sized intercooler and move up from there. The one you have is too small because its not dragging on the ground and hitting the top of the hood. LOL

Two the same size may work.

Most cars running low 9's are back halfed with tub chassis and ford style 9 inch rear. Yes you can do it with mods but usally its easier to just tube the car. Also your roll cage will need something to weld onto. Low 9's is a lot of new saftey equipment. Must have a full cage or your first 9 second pass will be the last at that track. Until your cage has NHRA cert.

Might as well toss in a 9 inch or at least a c clip kit. Once the cage is built you will have installed the sub frame connectors as part of the cage i would not put them in now. You will be cutting them out to install the role cage. unless your running in rules based racing you will be replacing everything behind the trans before you hit the 9 second mark. I am not sure how well a 12 bolt will do if running 600hp. I hope the 10 bolt is long gone it will fail and cost more to make right then a fully built shortened 9 inch with four link setup. That will run the number.

Here is a link for the general types of cages.
NHRA - Rules & Regulations, Class & Time Brackets - Hot Rod
power stroke core wont fit unfortunatly.i may however when the new engine goes in switch to a air 2 water intercooler i havent decided yet though, have to see how well the air 2 air core works first.


i skipped the 12 bolt or the 9 inch and went right to a dana 60
cage does not need to be welded to the frame conectors to be legal on a unibody car, just have to have steel plates welded down to the body for the cage to be welded onto


class rules say i cannot backhalf the car plenty of f-bodys with stock style suspensions in the 7-8-9's

suspension wise im setup with offset single adjustable control arms, lower control arm relocation brackets , tubular panhard bar , and 3 way adjustable rear shocks. my last purchase for suspension in the rear will prolly be a short tq arm setup from bmr.

need to play with the full sized tq arm first since the shorter arm will hit the tires harder

pretty much the exact setup a fellow board member runs with drag radials

update

ms1 cpu got here today , i unsoldered my stepper iac mods and had to redo my ignition control mods since the ms1 wont do stepper iac , and has a diff ignition system layout.

but the unit is ready to go

i am setup now with dual table use so i now have 2x 12x12 tables for fuel and ignition versus my 16x16 tables in ms2 so i have alot more tunning reslution now.

i have the tables setup to switch based on map sensor values my first table covers idle to around 12 psi , then it kicks over to my second table which is 13psi to 22 psi so i have lots of tunning points in high boost

unfortunatly my car is locked in my friends barn and he is in vegas till friday so when he gets back friday im going to get the ecm back in the car and hopefuly get to drive it around and get some videosdepending if i get to it before it gets dark.
dam headlight switch is not working so the car dont have headlights right now hopefully its just some bad wiring that the previous owner did that i can fix easily as ill be able to fix that on the spot, not so much if i need a new light switch


when the car does come apart for the good build i am going to replace the wiring in the entire car while im at it since the po really screwed it up
