It is not just 91 octane buddy it has alky injection and pleny of mods thanks drive thru.

 

I would steer clear of wiseco. Fwiw. Have you been searching around in the motor section? There are probably a lot more peeps in there running built motors than in here. Who's building your motor?

Whoa, man, <nachoLibre>Take it eassay</nachoLibre>.

Okay, so 20% is probly a little high. I don't think that 10% is a stretch though. Dynojets are notoriously high reading, since their method of measure is so inaccurate. Most dynos (that are realistic) measure torque (which is a valid measure of energy) where the dynojet just takes a set formula and measures how long it takes to spin their giant drum up to a certain speed. The torque number on a dynojet is derived from the horsepower number. This is opposite to the way it should be done. This is also the reason why the newer dynojets have gone away from this method and have now gone similar to a mustag dyno (more reliable and accurate results).

The Dynapack Dyno uses hydraulic pumps to measure the amount of energy (torque) that is being created at the wheels. This is much more accurate. The horsepower number (which we all know is a function of torque and RPM is then calculated from that figure.

Stomper's car is far from stock. The turbo is stock, yes, but that is about it. But even though the motor is built now, it made 390 when it was stock. We know the reason he didn't make more power was due to the turbo.

Perhaps you should read up on alky injection and its effects on octane (effective octane), iat's, and the ability to run more boost and timing (due to increased effective octane).

The uncorrected number is an accurate description of what power he is actually making at this altitude. That is the most accurate number. But to compare with guys at sea level and elsewhere, the corrected number is accepted as the horsepower of the car, since anything from a low-pressure to high-pressure, temperature and humidity can have significant effects on the uncorrected number. Do you think that the CA guys are posting uncorrected numbers? You should see all the sensors and probes the Dynapack has on it...lol.

I'm not trying to be condescending, or hate or anything like that, just trying to explain and answer the questions that you posed in your post. I welcome any comments or questions.

 

I think Mikes point was that the stock turbo can flow a max rate of 44 lbs/minute. Whatever octane you are running doesn't change that fact.lbx/min flow rate

I may be wrong but I believe a 44lb/min turbo will max out at about 410BHP.

 

That fact that any turbo will "max out" on horsepower is ridiculous. Some motors are more effecient than others, some run methanol, some alcohol. There is no "perfect environment" for a turbo to produce a "max power" or any power for that matter.

The manufacturer's estimate on where a turbo will make what power is just a guess. And a quite subjective guess at that.

Their flow maps are very accurate, but notice that they do not show horsepower numbers on any of those charts. It is all subjective "guessing."

 

Hopefully this contributes to the discussion at hand as horsepower discussions get quickly out of hand.

Da Basics:

Torque = Twisting --> Force <--
Horsepower = rpm x Torque x (a bunch of constants)

I always like to think of the torque (the force) pushing me down the road, and like to think of the horsepower as the amount of energy going into the system in order to keep my motor rotating at some rpm with some torque behind it.

Otherwise dyno readings start to get very confusing and "correction" factors start to take priority over other things.

Perhaps I'm going to have to start to ask eficker about "subjectiveness" but most of his arguments warrant technical merit.

So now the real question of the day is I'm coming to a point where I need to start upgrading the EVO. How far can I go on cams and turbos before I start to get ousted from certain SCCA classes? If I go with a set of 272s will I need to pop in head bolts, springs and retainers? The car is going to be receiving a bit of coil over jewelery (girls suck they don't need jewelery) which may already put me in another classification. Thoughts?

Cams or turbo upgrades will put you in Street Mod. This is a very competitive class and one where money put into your car counts, especially if you want to win. It is a fun class though, and allows a lot of mods.

 

My Dad and I are building it. We are going to do a little head work and the pistons and rods. New cams an intake manifold, turbo manifold, full exhaust, and maybe a few fuel up grades. New front mount and piping too. Then we will go from there.

 

hey everyone i am planning on hosting a track day for charity before the summer comes and would like to see if anyone would be available to do this. i was looking at 100-125 for a half day and 200-225 for a full day let me know what you think, you would also get a tax writeoff if you participated! pm me if you can do this and i will see if it is feasable

 

I am up for it.

What charity are you doing this for.

hey guys i am looking for wing for my s2k. here is what i am thinking.

 

i am still looking into charity's but it will most certainly have something to do with driving such as a charity against drunk driving or something along those lines. as of right now i am just seeing if their are enough people interested to make this feasable so i am expecting this event to happen in may if at all. thanks for your interest and keep it coming.

 

I see that Eclipse all the time on State. That thing is so HOT!!! JK. I dont know what makes people think that, things like that look good.

 

THAT WING IS SICKKKKKKKK! im going with that same exact setup but ontop of my wing.... that makes 3WINGS!!!! ill have the most downforce ever! and ill get all the babes!

p.s. hows the weather in utah? its hot here
cant wait to go there late march for a little snowboarding!!!

 

i'm in. i'm sure you'll find plenty of people to sign up for open track days here.

 

I really think you need to experience the ultimate in wing technology. Paper Mache.

please tell me how a turbo flows more then it is rated for???? to make more hp that is..... i made almost 470whp corrected which is @ sea level so all mike is trying to say is i really make lower 400's up here @ this elevation which judging by my trap speeds last year = true 3200lbs & 470hp=121.45 traps (not wheel hp)crank hp
