The heads are really the limiting factor on the car right now. I know I would gain a ton on the current setup just by changing them. But my question here is, what about spraying it instead? Am I asking for problems since the heads are already restricting me? Will there be too much crankcase pressure with the spray?

Or will a 150-200 shot be just fine on my setup? I've got the CR and block for it, but don't know if its a good idea or not.

Inputs?

 

Nobody? Anybody?

 

Is the spray just to get off the line or you planning to leave on the bottle and stay on it the whole way? Seems like it would annihilate the tires to me

 

The suspension is actually setup very good in my car. I can dead hook in 1st gear with cold Nitto DR's (yes, even with 614 RWHP). Don't know though if I would use it out of the hole though. I was thinking more along the lines of once in 2nd gear.

 

Here's a somewhat recent vid of my car in 2 races starting in 1st gear.

It looked like he took u in the 2nd race, and you in the first,.....so if im not mistaken, there should have been a rubber match?

An a little more on topic, I think you should be able to squeeze a 150 shot in there, but I wouldnt risk 200 just yet. See how it takes the 150 shot. I dont think you'll have any issues.

I think you'd do wonders with a slightly smaller cam or some better flowing heads and some more boost. Cam seems rather large 4 15 psi @ that flow rate. Better heads will likely drop your pressure, whereas I believe a smaller cam with a wide lsa would do wonders with the current blower and the 150 shot by keeping more cyl. pressure in. Either way, I think the spray will likely help you out as long as the engine will hold it (ie. head studs, splayed mains, and stable valvetrain (adequate spring pressure)). I say go for it.

I plan on hitting my s-trim 383 with a 150 shot, similar builds, but you have a bada$$ bottom end; mine is "adequate", hopefully, with an eagle crank and h-beams, and mahle -31cc pistons (2618 alloy). Let me know what you end up doing, very interested as to the results. Ive got a 350ci with 10 psi now, and I hit it with a 100 shot once or twice, and thats on a stock crank. Plan on hitting the track soon with a smaller pulley and play russian rulet with a 150 shot since my new shortblock is almost done. Ill let you know how that turns out.

Depends on how you look at the race. If you want to go by the rules that we do (1st one to the quarter mile wins, and past that its just for fun), then I won both times. He didn't go past me until more than 145 mph.

Not worried about winning races, also I am quite aware of the more power available with my setup. But I don't want to touch the motor at all. Just thinking of adding spray and how it would react with my current combo.

 

Sounds like you might be a little concerned with losing though.

 

This thread actually has nothing to do with racing at all (other than the vid I posted to show I can still get traction in 1st gear).

I am interested in keeping this thread on track with the original question.

 

Ok, so what really doesnt make any sense,.....well, theres a few things; Why do you have a pretty monstrous cam, WITH fairly meak heads, and is the D1SC maxed out? If not, the fairly obvious thing to do rather than spray it, is add more boost. Dont know the specifics of your cam, and I know you'er going to again say this is off topic, but I dont understand why you want to go about it halfass all the time. The engine is quite literally a mess. Dont get me wrong, yer car gets it,.....but it should/could be much more efficient if it wasnt a mishmosh of incompatible parts. Now you want to add spray to crutch the fact that its not setup correctly. How much overlap is built into the cam (read as: how much boost are you bleeding off)? Cranking up the boost (if possible) would be the most ideal solution to more power in your scenario.

What you'd rather hear: I dont think the spray will cause too much cylinder pressure with your CR and 10* duration split with that size cam and only 15 psi of intercooled boost. Not to mention the meth injection, although that is alot of **** to keep track of. I would imagine a properly matched 383 with a D1SC should easily put down closer to 700 rwhp with intercooler, meth, and likely more boost, but hey, lets slap another $500 band-aid on it and itll get there. Dont take this personally, I do like yer ride, just dont understand why you wont touch the engine. Spend the 250 on a custom cam for yer setup instead of wasting money on nitrous, and Id bet you'll net close to 70whp by trapping more boost in the cylinders.

 

...see, this is the bad side of posting a thread like this. All I ask is a simple question about spray, and I get people trying to tell me things about my own car (as if they know more about my own car that I don't) that have nothing to do with what I am asking.

No offense man, but I already am very aware of my current setup. I am not wanting to change it. This thread was not called "whats the best setup for my car?", or "what are your opinions to make my car more powerfull?". The thread is called simply "could I spray this?". That is what I want to know.

I shouldn't have to justify why, and why I don't want to go another route, or why I like my current setup just the way it is, or why I want to know if I can spray this instead of doing something else.

Now, once and for-all, for the love of all that is good and holy. Can we PLEASE stay on topic and get back to the original question?

 

From my reading thru the years I remember rskrause & roguedriver having forged rotating assemblies, moderate boost, & spray. They both ran 6 speeds at one point also.

I've been keeping up with this thread & was hoping that one or both of them would chime in here.

So I don't know why you would not be able to do it since they have done it.


Good luck
