#139 got two new mods today:
CF hood that came off #255/2000. No vents (and no rain water rusting up my turbo & manifold!). The fit is ok, but the curve on the front edge is too tight and doesn't match the angle of the fenders by the headlights. Oh well, it fits good enough. Uses stock latch, but Im going to put hoodpins on soon since the hood was already cut for them. It had some cloudy haze which 20min with a buffer & polishing compound took right off. It could use a little more cleaning/polishing work and a coat of wax, but Im happy.
The oem steel hood was just over 40lb. This CF hood with FG underside brace was 23.5lb. So it saved about 17lb.
Next mod was a single fogger NOS nitrous kit. Just have jets for a 50hp shot at 30psi fuel pressure (.037/.022). I'll have to back the fuel pressure off as I currently run about 48psi base which will make this run "stupid rich". Next year I'll jump the jetting up in the 100-125 range. The kit with a full bottle is about 28lb, which more than sunk the weightloss from the hood. /ubbthreads/images/graemlins/bawling.gif
It should make 5-6mph more with the nitrous on, which would put me in the 128-130mph range. More than enough to go in the mid 10's if I can keep up the low 1.5 to high 1.4 60' times without breaking the driveline again.
I got the mechaincal part of the installation done tonight:
[*]Bottle brackets mounted in trunk
[*]-4 feed line ran through interior
[*] Solenoids tested and mounted to firewall
[*] Upper ic pipe drilled and tapped for 1/16-27 NTP
[*] Fogger nozzle threaded on, all SS hoses and fittings are tight. (jetting checked 3 times due to OCD)
[/list]
Tomorrow I need to do the electrical half of the install which consists of wiring up a solenoid relay, a throttle microswitch, a main arming switch in the interior. I also have a bottle heater that needs to be hooked up, which is a simple relay & thermo-switch and I can pull the 12V from the fuel pump rewire. I also have a purge kit, but Ill likely save that for next year as Im going to remove all but the hoses during winter for daily driving after one trip to the track.
Bottle mounted in the trunk on passenger side. -10 SS vent hose that goes outside through floor in the event the bottle gets over pressure and blows out the burst disk. -4 SS feed line to the NOS solenoid. There's an electric heater under the blanket, which is a must for fall/spring use to keep the pressure consistent at ~900-1000psi.
Pics of the solenoids, fogger placement, and hose connections. The tuning jets are in between the fogger nozzle and the -3 SS hoses. Two wrenches are all it takes to change jets, going from as low as 25hp to as high as 150hp hit. Easy to get greedy. /ubbthreads/images/graemlins/devil.gif
Tapped the fuel supply into the -6 line going between the fuel rail and the aeromotive regulator using a -6 pressure gauge port adapter that I had laying around. Fuel line from there to solenoid is -4 SS.
I also picked up a Buschur 1gawd SS 3.5" complete exhaust. Basically brand new, still has the UPS label on it. One day next week Ill get the car up on the lift and see where it needs to be lengthened to fit GVR4. I'll bet the muffler is going to need to be rewelded too as it sits on an angle on a DSM and likely won't line up with the bumper shape for the muffler.
Here's my current engine bay:
Going to make one more attempt to see 10's this sunday before the car goes into winter daily driver mode. Wish me luck. /ubbthreads/images/graemlins/grin.gif
