I pm'd you

very intrested now, I like the way my car handles now and I know it needs a bit more tuning, but for power upgrades I think the same way you do and wouldn't mind a 100shot on top of my current set up.. of course I'm sure a clutch will be in my future at that point...

I wonder if i could hide a bottle in the trunk behind the false wall that hides the battery/washer fluid......

 

It just barely doesn't fit without the windshield washer tank. You could fit a 5lb in there though.

 

Must be nice to have that kind of $$$$$

 

Fair enough, I'm just not a big fan of consumable power adders but sounds like it can be made to work with the right setup. I'm making around 500 Crank HP on pump gas without cams and should hit 550 crank HP with Cosworth cams and some tuning so I wouldn't say I'm a couple hundred off. My turbo really isn't big either, I would consider it a medium sized turbo, 35R and beyond is closer to the big category.

As for highway rolls you are comparing my 1/4 mile times that are on pump gas at 27 psi with 4th gear RPM's limiting the run to 118-119 mph. My ET's are handicapped several tenths since I'm not a pro driver and the 19" tires aren't really the best for 1.6x let alone 1.5x short times. To say your car is as fast with "stock turbo, cams and fuel system" is misleading if you are using race gas and/or NOS to fly past me. I road race the car more often than drag race so NOS just isn't realistic (or even allowed) in most club racing. My car needs to be a reliable daily driver and be durable enough for 20-30 minutes of flogging at full throttle.

I can assure you that if I do a C16 Race gas tune at 35 psi against an Evo X with stock turbo, cams, and fuel system, you will absolutely NEED a major hit of NOS to stay anywhere close to the rear bumper. How much is needed I have no idea but at some point the stock fuel pump simply runs out of fuel and the engine flies apart as you know. I plan on hitting about 600 Crank HP easily with cams, intake manifold and a race gas tune with what I consider a reasonable tradeoff of response and spool. I used to enjoy autocrossing but after our local region stuck with smaller course layouts where my wonderfull AWD turbo car was barely ever in full boost I decided to settle on road racing to get my speed fix.

I wish you luck in your build up, sounds like it will be a nasty combo with lots of low end torque to match the high end horsepower.

 

I agree, but you came in wanting to compare weiner sizes Different strokes for different folks. You certainly have a lot of potential in your car on race gas. Drag racing is all about accelerating the car in the first 500 feet, and this gets it done for me. Plus all the suckers on the street think its a stock car and it pays!

 

It doesn't take money, just a lack of brains and a patient wife!

 

If you did want to hide a larger bottle...there is a nice large spot where the spare tire is when it's not in the car...I'm just saying...

 

It doesn't fit

 

Sorry if my first post came off that way, but yes we have two different goals with our Evo X setups and your combo should work nicely. One thing for certain that I would beef up on your build is the fueling. If a 100 HP shot of NOS really adds that much HP then you need the fueling for 125-130 mph trap speeds in the quarter. That HP level alone HAS to be close to the absolute limits of the Stock Evo X fuel pump let alone the ~600cc injectors.

I know you are making more power in the low to mid range compared to the top end with this combo but if a 200 HP shot is really adding in that much power on top of the 450+ crank HP you are making on race gas then fueling is cheap insurance compared to running lean.

Just me helpfull 2 cents.

 

You didn't come off in a negative way...its all in good fun

You are fueling the car different. I'm adding all my fuel for the extra 150-200hp through a direct line and a nozzle, not through the injectors. I run 12.5:1 and leaner off the hose and tune the nitrous AFR with the fuel jet itself. On the 150 shot, I was 11.5:1 AFR and not falling. If I want to run leaner, I just run a smaller jet, richer, larger jet. On the 200 I saw 11:1 then POW so who knows if it could keep up.

Either way, it is apples to oranges when comparing to a larger turbo car adding the fuel through the injector. I only need enough injector to handle the power the car is making off the hose.

 

Ah shows how much I know about NOS setups, makes sense that the additional fuel you need is injected with the NOS seperate from the rest of the fuel system.

 

Nice. I have been waiting to see if you would post your n2o experiences with the X.

 

Wish I had the money to test the limits on the motor.

 

You should bring it back to the dealer and act like you don't know what happened, that would be funny.

 

Well at first I'm thinking Wow.....this guy is an idiot. Well after thinking about some more I've changed my mind. We all obviously know that spraying that 200 shot was not the way to get it done. I'm all in favor of guys using nitrous if that's what their in to. Where it getsto be a sore subject is when the N20 guys are talking smack about a guys turbo setup saying that he's making way more power for less. Nitrous isn't for everybody but it would be interesting to see what a small shot would do on my setup. Good luck with your setup and hopefully you'll be in the 10's in no time.
