ull probably lose 20hp in 4th but still great numbers

STFU oso. Where do you come about telling him to leave? 400 hp on a budget build = definition of HMT... :y :6

Dude, seriously, what the ---- is your problem? Throughout that whole thread you were bashing kevin's hatch talking about how it wasn't possible, and it was fake, and his setup was bullshit, etc... But now you went through and edited all of your posts then linked to the thread to prove some stupid point. You are ------- stupid as ----. What happens in a month when someone breaks 500 hp on a d series here? Are you going to edit all of these posts to act like you agree with this kid then link here to prove that you can only make 400 hp? Again, I ask, what the ---- is your problem?

I dyno'd at 323whp at 17-18psi with t3/t4 50trim and .48AR. Hind-sight tells me that my 6" JRC intercooler was a significant restriction too.

But i think 400whp is right in line with the whp i made and the other guy with the vitars setup over in seattle, 354whp?

JD, since this thread has already gone to ----, i guess it won't really matter if this is OT.
I'm currently running alky injection with my Vitara setup, i notice that there is a huge seat-of-the-pants HP jump going from 11.5 to 11.8-12 A/F. I'm running just a hair over 25% 50/50 mix with my 450cc injectors.

I have a suspicion that i could pull even more fuel, but i just want to bounce ideas as to what other people typically run for A/F, 12.3 range a/f?

Re: Joined the 400hp SOHC club...on vitaras!!
 

is that with just vitaras?? Or aftermarket rods too??? ANd what kind of gas are u running on 17-18psi?? Pump gas?? Or nah?

Re: Joined the 400hp SOHC club...on vitaras!!
 

D16 knock limit on pump seems to be around 350 whp, a little less if you use a log manifold. Water injection will give you 10-15% more knock limit in 50% water:fuel ratios, racegas even more.

Alky runs hella cooler than gas when it burns, and water has four times the cooling properties of alky (latent heat of evaporation blah blah blah). A rich mixture just uses unburned gasoline as coolant.

Sounds like you are cooling combustion reaction so it's burning slower = needs more ignition timing. When you lean out .3 AFR the ignition timing starts coming back in line. There's also a chance you have a little misfire action going on, are running richer than 11.5, and the misfires are leaning out what the wideband reads.

I'm completely totally clueless what you mean by 25% 50/50 mix. Until I know what and how much you are running I can't really advise what you should do with any confidence, but YES people have leaned out big power cars almost to stoich and let water do all the cooling. Just keep in mind that if you make more power (heat) than your level of water injection can handle, the water dissassociates into H2 and O2 and your wideband readings reflect anything except reality - at those temps the H2 and O2 don't react with each other, but seek out Al and Fe aka consume your engine, which is why detonation leaves "pits" in the combustion chamber/piston... for every pound of gasoline consumed you get two pounds of water, and the overheated + dissassociated water chemically reacts and consumes the combustion chamber/piston in a very high energy explosive reaction. Irvin Glassman's "Combustion" gives good details on this, covers using powered metals and metal slurries as fuel.

I think I've babbles semi-incoherently, thanks to five cups of coffee. Gimme more details, give me an idea what you're unclear on, and I'll crack at it later tonight when I've calmed down.

I can build 500 whp B-series swapped car for $4000, buy KY jelly for when your gf comes over and I ---- her in the ass, and buy your gf breakfast the next morning. There is no excuse for being stupid in the day and age of freeware tuning tools based on cheap parts. Better driveability, better safety, more power.

I hope you aren't claiming your fishtank valve'd MAP sensor car is faster than the one you've been cracking on?

There's no reason to ever run hacks, clamps or FMUs in any car.

Re: Joined the 400hp SOHC club...on vitaras!!
 

Wrong.

Mk3 and Mk4 turbo Supras. The MAP sensor in those doesn't do what you'd think it does, since it's a MAF car. Voltage clamp pls kthx! :P

Re: Joined the 400hp SOHC club...on vitaras!!
 

high powered v8 cars use fmus a lot cause huge injectors are too expensive

Re: Joined the 400hp SOHC club...on vitaras!!
 

High powered V8 cars also use smaller ratio FMUs so that they don't get stupid fuel pressure problems that causes inconsistent fuelling.

Apples oranges.

Re: Joined the 400hp SOHC club...on vitaras!!
 

i used a 12:1 on mine, i think the fuel pressure was in the stupid range though haha

Re: Joined the 400hp SOHC club...on vitaras!!
 

Mark McKay ran 370cc injectors and 4:1 or 6:1 in his yellow convertible shortbus when it was SC. He was happy as a pig in ----, raved about FP being predictable.

Re: Joined the 400hp SOHC club...on vitaras!!
 

JD,
good info... although i'm gonna have to let the later half sink in a minute.

I'm running a 5gph nozzle (5 x 63= cc?). Which is close to 25% alky injection to my 450cc injectors at 85% duty cycle? I use a 50/50 water alky mix.

So basicly what ive done is trimed back fuel in the load ranges that alky starts to spray. My a/fs average about 12:1 right now.

as for timing goes, i'm about 18* total timing @ 15psi, and 15.5* @ 19psi. So far no signs of detonation. So is it safe to say that i could tune a/fs closer to 12.5 without running into the condition you where talking about that completely went over my head. :D

Or would i be safer to start toying around with ignition and leave a/f as is.

sorry about the newb questions. I thought i understood it, then as i started to read more info online i totally got even more confused all over again.


P.S. this is on a Vitara set up.

Re: Joined the 400hp SOHC club...on vitaras!!
 

So at the point of H20 dissassociating, are you just pointing out an extreme case that i should be aware of, or is this a level easily bumped into. From what ive gathered it sounds like it must be a very extreme case?


One of the reasons i'm asking all this...

heres my track results.

60ft--------- 2.05
1/8ET------ 8.4
1/8mph--- 91.48
1/4ET------ 12.86
1/4mph---- 112.27

The 1/8mph is healthy but the trap is sucks... i just wondering if the top end is getting hosed down or what... from inside the car, as far as i can feel everything seems ok? This + the fact that there was a big power jump just by leaning it out .3-.4 a/f, is it possible up top is still not in its optimal timing/ a/f range?

Re: Joined the 400hp SOHC club...on vitaras!!
 

Yes, very extreme. It's called detonation. Regardless of whether you have water injection or are just running gasoline, detonation is hand in hand with dissassociated water. You are *safer* with water injection, but some people start thinking bulletproof when they've made no attempt at figuring out how much water/alky they are injecting and get stupid with the boost controller, AFRs, or ignition timing. Just because you have permission to lean things out, turn up the boost, dial timing forward doesn't mean you shouldn't do it in very *small* steps and keep your eyes wide open.

The size of your nozzle is great, but what is the water pressure? Dose the water pressure ramp up as boost comes up, or does it stay the same and you get less water as it fights the manifold pressure? It's awesome to see you've sat down and done math on your car, but I'm still a few sticks shy of a load.


Yup, it is.

You're doing part water injection, and part fuel substitution. Figure 2 parts alky equals one part gasoline when you go to lean things out a bit, right now it's skewing your wideband's AFR readings... which direction is it skewing things? After you've figured that out, we move onto: 12.5% by volume water:fuel ratio, the cooling from which is slightly modified by alky's cooling properties. Tune your ignition timing accordingly; it might be time, after setting alky-corrected AFRs, for dyno time. Keep in mind when dynoing, that while water injection does it's deal by directly cooling the combustion chamber (it does not cool charge), a small bore D16 builds up heat. Normally you take one pull to heak soak the engine before you start paying attention to numbers (cold engines make more power), I'd do two and maybe three once you step up to more water/alky. It's not a lot of water injection @ 85% duty on your 450cc, but since you aren't at 85% for a lot of your boosting it's a pretty good dose of water/alky.

It might be an idea to do a second stage of water injection based off MAP/opamp switch or Hobbs switch. I don't like turning on a huge nozzle and having a fixed flow make water:fuel ratios run all over the place for a variety of rpms and loads.

Good stuff.

Re: Joined the 400hp SOHC club...on vitaras!!
 

I'm using the Devil's Own alky kit. Its got the progressive controler, which starts spraying 15% duty @ 8psi and ramps up to full duty @ 14psi. Its got the sureflow pump. I have it start spraying kind of early b/c i noticed that the pump isn't as fast acting as i'd like on highway downshifts.

http://i6.tinypic.com/1zqsytd.jpg

You know... the last time i dyno'd i actually ran out of injector on the dyno and hit A/Fs of high 13s @ 18psi. Thats the first time ive ever seen shiny specles on any spark plug, now i know what it looks like :P several compression tests since then, with weekend beatings, have shown good compression. If it were not for the alky/H20 i think my motor would have been toast for sure.

As far as figuring out what the H2O and alky is doing to my WB readings, i am still confused. Ive just been relying on WB readings. Can you point me in a direction as far as alky/water corrected A/Fs?

thanks a ton...

i have kind of been going about this on my own except for the little usefull information i was able to find on turbobuicks.com and srt4forums. Everyone seems to just preach, "just run 100% meth!"
