Default supercharged + nitrous

if i were to put a d1 kit on a 355 lt1, looks like it will be outa steam somewhere in the 700's so to make more id like to spray it with maybe 100 shot, assuming it doubles i should make 900ish

what ill effects do you have with supercharged and nitrous cars, i know with turbos you run into backpressure problems when your maxed and then try to spray

Properly setup (8rib, overdriven balancer, etc..) the D1 should be able to make high 700's and some I've seen make in the lower 800's. With that being said I would overspin the D1 with an 8" balancer and a 3.5" blower pulley. Then spray an 100 shot on top of it. Boosted cars love n2o. Should be able to pick up over 150rwhp on a 100 shot!

Also the biggest herdal you will have to overcome is the fuel system. This will require a great deal of fuel.

I spray a 100 shot on a maxed out g trim kit and have never had a problem. There is a number of us who race every weekend at the track with either a procharger, vortech or kenny bell and well all spray on top of our blowers. The rule is two power adders max.

I agree, the car is going to need a good fuel system which isn't cheap. 700 rwhp or so can get by without going with a whole new fuel system, but somewhere past this number requires a lot more fuel. Bob

Wet shot is easier to provide the additional fuel.

A 50 shot (with about 900psi bottle pressure) on top of my 8psi of boost gave me an additional ~50rwhp and ~125rwtq on a Dynopak dyno. N2o torque multiplication on top of boost is pretty stout...

My 100 shot picked up exactly 100 peak to peak FYI.

I run a separate fuel cell so I don't tax my fuel system.

Theres NO WAY in hell you will be out of steam at 700 hp on a D1. We just made 1000hp with a true D1 unit spinning it to 8000rpms. Something is not correct with your setup for sure.

Its a planned setup from what I know, its not done and running yet. I think you will get where you want to be Daniel on boost only, just leave the kit on the car in case you need it.

I would find a 1 7/8 or larger header though for those power levels.

Is there any other risk to spraying a boosted application, other than the obvious form increased stressors on moving parts..(provided fuel is adequate)

im not a fan of superchargers at all...but lt1 turbo kits suck...not one nice one that id be happy to run...
and the headers is a whole nother challange


this whole idea might get scrapped though since lt1 computers can only read 2 bar...it wont make the power i want at that, not a huge fan of dropping the money for bs3...

Agreed 100% I had to run to Walbo 255's in tank and bigger injectors it costed me around 700 bucks for injectors and 2 Walbo 255's. That is a definate thing you dont want to short cut or not upgrade!!!

Sorry but my D1 was DONE at 750rwhp in my well setup 402ci application. I'm pushing 14psi through it with a flip drive. I may be able to eek out a little more with some gnarly AFR225 type heads instead of the 6.0 heads I'm running, but the D1 is huffing and puffing.

I through a 100 shot on the car instead and the power under the curve now is retarded.

Like they said above, fuel is going to be key.

Best bet would be to run a stand-alone tank with the spray and fill it with C16 or something.
