200 I-6 on spray

[Anonymous]

New to the 6 cyls, just curious, have any of you guys run spray on a 200 I-6?
How much do you think one in good mechanical state can handle?
I've got an 80 mercury capri with a 200 and a c4.
Looking at trying to get it to run mid 12 on the bottle.
Possible?
or drop in an 8?
like i said, never had experiance with I-6s before, my last stang had an 11.5:1 comp 306 with a 200 shot, so any help would be great about where to get parts and what works and what doesnt
Thanks in advance, Dave

Alex (Mandarina Racing) runs nitrous on his. Runs close to a 14 flat. The only way you are gonna run 12's on spray is to do it with Mikes new aluminum cylinder head when it comes out.

I was talking to some guys on another forum about what they thought and they thought it was a bad idea to run it with a log head?

Who knows....try it and report back to us with the results!

Later,

i think a small shot would be ok with a log head but not great a direct port shot would be alot better cause itll be evenly distributed and in order to runs 12's your gonna need a minimum of forged pistons to run the amount of nitrous youll need to get there

I know what you mean but i think if you could some how equalize the distrubution to all cylinders you should be good to go?
When will this aluminun head be avail?
Any idea how much and where to get it?

I was thinking of some sort of boxed custom intake and a big cam with a set of 2.3L turbo pistons and a header, should give me about 10:1 comp, get the head to flow and give it about a 150-175, shot and see what happens

Well, Why don't you try putting a 150 shot on your stocker and see what happens.

The only problems I can see that would be specific to the 6 would be related to poor distrobution causing some cylinders to get more than the others, putting them under more stress.

A direct port setup would fix this, but would be a lot of work modifying the head (altho really, you could almost just drill and JB weld the injectors in)

Other than that issue - the motors are strong and can take a lot of punishment. Should really be perfect for a Nitrous motor.

As for the AL head, refer to the sticky at the top of the page.

thats kind of what i started thinking but with alittle more comp, better cam, worked intake and a header, it will breathe much better and take more advantage of the NOS, sounds simple enough, but I'll bring a broom and dust pan just in case, lol
Any idea if a 302 torque conveter will bolt up to the 6 and fit in the bell housing, looking around 2800 to 3200 stall with a 373 or 410 gear out back, slicks and some suspension work, hopefully if it dosent puke it self all down the track it would make for an interesting pass

no go on the convertor. the 200 has the gear on the TC not a flywheel.

2.3L OHC pistons won't fit in the 200 block (bigger bore ont eh 2.3L) 2.3L HSC pistons will (tempo/taurus) not liek 2.3L ohc turbo pistons (looking for the forged slugs I take it) are that much cheaper than custom slugs

Now you guys have me thinking of a 50-75 hp shot of nitrous on my stock 200... 8)

Here's a thought...for what it's worth.

Instead of drilling/tapping 6 holes for nozzles, couldn't you pull the plugs out of the ends of the log intake, and use those openings? Lot less obtrusive, and if you could just use the back one, it'd be pretty stealthy.

How about getting some long thick-wall copper tubing, and making "nozzle" openings that'd line up with each intake port? Make up two - one for nitrous and one for fuel. Kinda like a nitrous plate, only a lot longer.

Use the end-plugs to locate the tubing inside the log, and away you go.

 

[XFlow_Fairlane]

it could work...but I think it would intrude on airflow while NA.

I think someone makes a straight nozzle....you could put them along the side of the log spraying down the runners. drilling and tapping would not be a big deal if the head is off the motor. I had thought of putting my injectors there when I was making my EFI head but figured they would be too far form teh valves and I woul dget some puddling in the log.

I've been thinking of three of these on a 3x1 Offy:

...

I'm thinking you could locate them towards the 'backside' of the log, towards the passenger side of the engine. Apart from being to the side of where the carb sits, they'd be pretty out-of-the-way.

The manifold log has freeze plugs at each end. Modify the ends to accept a long spray bar with a nozzle squirting into each of the six runners.

that would make for an interesting setup but could probably be made to work if you evenly spread the holes.

why not set up something like a cold air intake and spray it before the carb? NOS makes a kit that sits right on top of the carb and sprays inside the air filter, but that kit is only good for about a 50 or 75 shot, It wouldn't mess with the carb, it doesnt know whats going through it

I THINK this would work if you came in from one end (from the back for stealth) with both an NO2 line AND an extra fuel line. However, you would have to be very particular on the port spacing, AND, it would somewhat restrict the air and fuel flow when not running under "the bottle".

Just IMHO.

not to hijack the thread.

I used to have an 80 capri with the 6.
If it's straight and rust free, don't swap in an 8, offer it up here first.

I can't get a car right now, but will be looking for an I6 capri in the next year or two.

a 100 should be safe with a 2v carb with a larger secondary.

a t5 would also wake up the engine as the c4 while solid eats a bunch of power.

I would beef things up a bit if you are going for 150 or 175.

The head is going to be your downfall here.

The aluminum head should be up for order "soon", predicted price is 1500 or so.

Hmm...now that sounds familiar...
