Fastest Stock Block Msp Period

[Lodivigo]

I am thinking of removing the stock interwarmer in order to keep the turbo in efficiency range a bit more, seems if I am boosting 14psi, the turbo is actually working maybe 16-18psi before the IC restriction. Most people running a system like this in their drag cars are hitting 30+psi without an IC btw.

Holy crap, you're still running the stock intercooler at that boost level?!? You are asking for a blown motor. At least get some kind of SMIC that works with the stock piping. Pretty much anything you choose is going to have less pressure loss and be more efficient than the stock intercooler; and it'll still "appear" stock.

Good luck man, hope you know what you're doing...right about now your rods are screaming for mercy.

Good luck, lets see what you can run. Hope that you can get your hands on some good fuel up there.

Subbin ... I can't wait to see the outcome ...

Sounds like you got a plan that needs almost perfect implementation.

Hey Jeff, I think ive seen you booting around Oakville, love to see your setup, im just working off Winston Churchhill in Oakville, im running about 13-14 psi..with the stock interheater...should meet up the one after work

Doesn't a wb measure lambda and convert it to an afr reading based on the stoichiometric ratio for gasoline? Were your afrs showing a more rich ratio when they were actually lean? Are you going to run a 50/50 water meth mix? I just got a snow stage one kit so I will be playing with this stuff shortly.

ok I made 2nd pic an attachment a few posts up, 1st shows up for me I dunno bout u. maybe cardomain is having problems.

pretty sure technical term would be something like individual port digital methenol injection system

and btw dont ever try to tune something like this with a WB02, it cant compensate for the different fuels, you need a Lambda gauge, trust me on this lol!

chemical intercooling is more efficient then air to air. The intercooler is actually an interwarmer compared to what methenol injection does.

upgraded IC = beh. Trust me Ive had a fmic, see sig. injection does a much better job.

Just to let you guys know since it seems most dont realize whats going on here:

when you inject the following things happen:

1. the intake temps are lowered as the air is chemically intercooled, depending on what mix of water/meth you are running it will cool the charge accordingly.

2. Combustion temps are lowered

3. Exhaust gas temps are lowered

4. Highly potent fuel is added to the charge. The detonation resistance it adds is spoken to be higher then 116 race gas depending on your mix.

5. Cylinder heads temps are lowered overall.

There are a few other points, but that sums it up for the most part.

Methenol fuel dragsters run 30+ psi with no intercooler whatsoever. The T25R will never be able to heat up the air more then the injection system can handle.

If you guys remember from my old posts, on the old motor I was running 14psi for quite some time, no problems. With very poor tuning and only a single needle mounted just before the throttle body.

The new system is tuned quite well even with my makeshift controller and can supply more fuel/cooling then any streetable turbo can throw at it.

exactly, you need the lambda meter unless you wanna sit down and do a whole shitload of math figuring out your WB readings.

Well, I honestly don't know much about meth injection.
I have a few questions:
Is this going to be your daily driver, or just a track car?
If you remove the intercooler totally, while driving daily (or period) that would mean; meth would have have to be constantly injected. If you run out, or there is a problem with your setup wouldn't the higher intake temps due to no type of intercooler cause detonation?

I agree that it sounds like a good idea, but it isn't practical for a street daily driver. Besides, pure torque can destroy the engine, not just pre-detonation. An FS-DE will eventually fold due to the stress of added power. Still interested to see how long it lasts.

Jeff- this is kind of interesting:

[210_ZOOM]

are you gonna dyno run it?

 

[Lodivigo]

Nice info, I'm in the dark about chemical injection as well. I still think your engine is on borrowed time though. Your rods are not gonna last long making this kind of power.

 

[Pirana]

Makes ya wonder why ya spend so much on aftermarket parts dont it hehe

Nope (nervous)

Good stuff...me and Sam have been running stock blocks for over 18 months...and yes we have been spankin STis...so its doable.

 

[LordWorm]

Methenol fuel dragsters run 30+ psi with no intercooler whatsoever.

Most of the ones I see around here run a dry ice box intercooler......to maintain sub zero intake temps over the quarter mile.

and they run well in excess of 30 psi...30psi maybe on the launch....2step FTW!

 

[Speed_Racer]

i wont join the "zoom zoom boom" bandwagon, i'm just waiting for the rod knock.

meth injection is going to add some serious mass to your charge air. Just don't forget FS rods don't like torque, I wouldn't use meth from too low of an RPM if I were you.

Good luck keep up posted.

i already know the rods will be the first to fail, its a question of whether or not it will hit a 12.x and dyno higher then MAM 267WHP stock block. What can I say, I have spare everything and the knowledge to rebuild the motor so why not. Last motor lasted ~100,000KM with similar abuse, sure this one will get at least 50,000KM of fun before either the rod bends or worse. Then I have to spend 1 night swapping a block, oh well. Guess I will only get to drink 12 beers that night and not the whole case lol

you will have to dyno higher then 277whp actually....

looks nice (humpleg) Well theres the record to beat. lets see what happens.

would be a nice record, but its not very practicle considering not everyone has spare motors and the knowledge to install them. why not just upgrade the block and the rest of the turbo system, then try to set the record of most whp EVER attained.
