How come I don't see more a4 guys running alcohol injection? We could run higher boost on pump gas.

and

What about Variable intake manifolds? This could give us better mid and top end power; switching from short/long runner.

How would you apply a variable length runner set up w/o completely replacing the current intake manifold?

probably because that 2871 Eliminator on race gas may hurt those skinny little rods. running W/A injection lets you push big power like that everyday. it might last, it might not.

it seems like AWI might be a better idea on a K04. that little heat gun can use all the cooling it can get. your 2871-E intake temps are probably lower than a K04 even with 100 hp more.

So what happens when you racing and all of sudden you remember " OH shit did I fill that tank up" and BOOM the motor blows because your running timing set for the W/ A mix not the gas in your tank. I think I will take my chance on real tuning on the fuel I have before I start looking into things to cool my IAT's more then my FMIC can.


Who here makes enough power to say the stock intake manifold is an issue?

Variable intakes are for natural aspiration only. Forced induction already forces the air in, no need for flaps or any of that crap to get in the way. The new 2.0l uses some tumble flaps mostly to improve cold idle quality....

most WI setups use the stock washer fluid tank. this lets you use the stock fluid low warning light. pull from the lowest point so that if the light comes on you still have a little juice left. if the light malfunctions and you run out i'm sure something will let you know...

What was the point of that dyno plot you posted? That car doesn't run WAI at all, it runs C16 and that pull was on 27psi.

your friend?

i got that from my friend too (his evo...)

Would your friend happen to be Tom also know as SmogRunner? If so he lives 6 houses down from me.

nope.. he live in chicago...
i believe that dyno was done at ams..

Odd, because it says Smoggy35r and those are his exactly #'s he put down on the dynojet at Tuning Technology.

hmm..
i will tell my friend to check on ams if they gave him the right file..

weird..., but y would ams have that file? and gave it to him?

mike-2ptzero
03-18-2006, 09:48 PM
Maybe your friend just gave you the wrong file.

If I remember right that plot is of his best 91 octane and C16 runs, he was the first to put down 539 whp while still running the stock maf.

Is your friend running a 2.3 stroker with a GT35r kit?

Elf4U
03-18-2006, 09:51 PM
not sure on the engine, but its the 35r kit...
he has the menthaol injection.

mike-2ptzero
03-18-2006, 09:52 PM
Actually that is Tom's dyno plot which is posted on EvolutionM.net making 539 hp and 492 tq at the wheels. Here is what it says when you Yahoo search it.

On race fuel, we made 539whp and 492 torque ... Nice job smog ! Stroker is bad ass

No I am just saying that is the exact power Tom "smog Runner) made on the dynojet at Tuning Technology. That dyno plot has been posted on EvolutionM.net which is most likely where your friend got it from.

Well I know you could run out of alky and go boom, but thats one of the many dangers of tuning cars, and thats why you have to put safeties in place.

Its just that us a4 guys don't seem really adventurous with little tricks like that.


Intake Mani:

You would probably have to replace the whole manifold but I have seen cars that gain like 30 whp by switching from their stock mani to a variable mani. Granted the car in question was N/A from the factory, but runs turbo/SCer and sees major gains from the variable system.

onemoremile
03-19-2006, 02:44 PM
some cars see gains and some don't. i know a lot of VR6 guys spent over a grand on a Shrick VG manifold and only saw a marginal improvement. for the money, i can't see why people buy those things.

i'd rather sweet talk the folks at USRT into making a large plenum mani but i'm hardly in need right now.

take a peek at the 1.8t engine forum on vwvortex. apr is showing off an exceptionally expensive manifold using an $800 RS4 throttle body. 899 without TB, 1699 with. yikes!

I will make sure to post up after I test out a new manifold for us A4's.

2.8's have a variable intake manifold system. the g1'd supercharged guys disable it in order to help more air flow. for us G2 guys, its not a problem anymore [;)] .

i have a water/methanol injection system on my a4. i have it disconnected right now because it is winter, and i am having issues getting a good hardpipe fabricated to go from the intercooler to the throttle body..i wish i could weld aluminum..

on a slightly aside note, maybee not, Rick runs water injection on his supercharged 2.8 with the smaller 2.8" pulley that puts him at around 10-12 PSI. he runs it out of the washer fluid resevoir and has an arming switch mounted in the cockpit to control whether the automatic sprayer is on or not. last time we went to the dyno he did some runs with it both on and off. there was no noticable difference in peak horsepower between runs, but the water injection seemed to slightly increase and smooth out the midrange hp/torque numbers. more importantly, running the w/i dropped his steady state intake temps almost 40 degrees on the highway and boosting temps from just over 200 (eaton blowers are not very thermally efficient) to around 130 or so, if i remember correctly (give or take 20 degrees on all numbers, i'm too lazy to go find them). when i drop my pulley size i plan to run w/i to keep temperatures under control.

of course, everything i jsut said applies to s/c 2.8 where intercooling is, as of yet, not an option. like mike said, i see no reason why a FMIC couldnt give a turbo car sufficient cooling to prevent problems. just offered this as another perspective on water injection.

FMIC alone might not be enough to run like 26 psi (gt28rs,2871r,etc) on pump gas, but I get your point.

That means they have the wrong core if it is heat soaked all the time in that condition.

I wish i had dynos i could show but my friends turbo'd omni picked up 45hp at 26psi with methanol injection, mixing his own 50/50 with water. He's got a progressive kit from Devil's Own and tuned it in with his wide band and F.A.S.T. setup.

and you've got the wrong turbo b/c you're running it way off it's peak

I guess your talking about running 26psi on the GT28rs and GT2871.
