The Trap is VERY VERY low for those mods. I should be atleast 110MPH.

 

how did you launch at 6000 If you didn't know about the rev limiter? It must be unhooked to launch at 6k. Your technique of slipping the clutch to launch is not doing you clutch any favors nor your 60' time. Your 60' times are poor and are one reason your et is .3 to .5 off. Your trap speed has little to do with your launch. So 104mph gives you idea of how much power you are making. Was this a run on pump gas and if so a race gas map and a better launch would put your car in the mid 12's which isn't so bad for a tbe and a flash. Enjoy. Side note On my 03' when I got a xflash from vishnu I felt it in the drivers seat. The car was faster and smoother.

 

I am not a big fan of the mail in flash. If you can I would advise getting a custom tune via EkuTek or something to that effect. My personal opinion is that you will gain more hp and tq and it will be designed around the specific mods that you have, not just a generic map according to previous tunes with similar set - ups.

 

I don't think that the mods I have on my car are so exclusive that it would require a dyno tune. I realize that it is possible to squeeze a little more out of it, but to me it's really not worth $500+ when all I have is basic bolt-ons.

I do not know why my trap speeds are as low as they are either, I was expecting them to be between 108-112, but I was consistently hitting 104. This is on 93 octane Amoco gas...could be lower because they're mixing ethanol into the gas these days. I had 1/4 tank of gas when I was at the track.

 

I did say around 6000 RPM - I'm not watching my tach, I am paying attention to the tree and also where I am driving my car.

I do know about the rev limiters, I just never heard of a rev limiter refered to as "launch control" (system for firing rockets/missles) or "2 step" (an easy to learn dance). Anyway, I tried using secondary rev limiter to launch and it worked pretty good...but I'm wondering how much of this the stock clutch can take before dying. Is it better just to dump the clutch at launch even tho it puts a harder shock on the drivetrain?

I also removed the restrictor pill from the BCS hose under the airbox. Now I'm definitely getting more boost, spiking close to 1.5 bar. This is something I can feel. As for my trap speed, I'm guessing that is a result of pump gas with ethanol in it...either that or something wrong with my car.

 

FYI, all 05s and 06s (RS, GSR & MR) come with the duel stage @ 5K, not just the MRs.

 

Of couse a custom tune is better then a mail in flash. THe custom tune doesnt have to be done with super expensive software, ECUFlash works just as good, if not better.

 

launching a awd car is not the same of rwd or fwd it takes practice, your 60' time is for the newbies I know I did the same thing, I got flash by Jestr too the first time it was the basic flash and I feel the difference, I just got a costume flash from Jestr last weekend and man can't wait to hit the track the car is a BEAST, so back to the point is your driving PRACTICE

 

The car is just slow. The ET is irrelevant, because that's just really poor driving. Actually, the driving (shifting) is pretty good, but the "launch" doesn't even deserve the name "launch," because you were not launching at all according to the 60's. If you were terribly bogging or something, then maybe it was affecting your traps, but you still should be much closer to 110mph, especially in this colder time of year.

The HFC isn't helping, and having an exhaust/tune without boost control isn't helping, but the car is no faster than stock. I doubt it's the tune - that part's easy.

 

Thats a good run other than the 60ft time. I have a bone stock IX MR and I ran 8.6 in the 1/8 mile with a 1.8 60ft time.

 

Uh...dude, read the previous posts. I didn't launch it hard because I didn't want to, nor was I using he rev limiter to launch. It was a simple 4K slip and go, which does not bog. 2.0xx isn't GREAT but it's certainly not bad either.

Why would I need a boost controller if removing the pill has me up to 22 PSI or so. I doubt it will go much higher if I were to put a BC on there.

As for the HFC, how is it not helping? Last time I checked, a larger diameter + better flowing element would be an improvement. Not as good as NO cat, but smelling exhaust fumes when i'm driving around isn't my thing. A good HFC definitely better than stock.

The trap speeds remain a mystery....

 

I did read the rest of the posts. I do know you said you didn't launch hard, and I said that you didn't launch at all. There is no reason to go to the track and especially no reason to come on here and whine about your times if you don't even bother to launch. We're talking 2-3 launches...big deal...launch that sucker right and get the best time possible. You said you also launched AROUND 6k yet somehow only got a 2.1. I don't know how that's possible. I do know that "launching" from 4k is useless.

Pulling out the pill doesn't magically give you reliable, consistent boost. It gives you a higher spike, but it still has the stock taper that is much more drastic than with an MBC, and the taper is what you have to worry about most when drag racing, because we are never below 5500rpm. You may see a 22psi spike at peak boost (~3600rpm), but you aren't seeing 22psi on the drag strip...

Blah blah larger diameter, better flowing, whatever. An HFC gives almost nothing over the stock cat - both are very restrictive. I have never smelled exhaust fumes while driving from running with a test pipe in 5+ years with DSMs and my Evo. I can think of several reasons not to run a test pipe, but worrying about smelling fumes is about as lame as launching from 4k rpm.

Anyway, I'm just giving you direct feedback. These aren't insults or anything personal.

Oh, btw, you said "2.0xx isn't GREAT but it's certainly not bad either." No, 2.0 is disgustingly awful for an Evo. Any 60' that bad means the run cannot be looked at, because everything is thrown off so much from the non-launch, and that includes your trap speed. If you care this much about how well your car runs (or doesn't run), then go back to the track and do some REAL RUNS. Cut some 1.7/1.8 60's and shift your *** off. If you still only trap 104, we know there's a problem. Don't go back before doing a boost leak test, though.

 

Warr is right, teh trap tells the story. Go get a MBC, you probably have 15-16PSI in the Higher RPM's. You should hold it to 22PSI, which would give you a MASSIVE boost in power and your Trap speed.

 

Not hitting an ideal 60' doesn't mean it wasn't launched. It just wasn't launched hard. Are you suggesting that you have mastered the art of launching so much so that you are dominating every bracket racing division out there with your robot-like consistency? Somehow I doubt that.

The higher RPM launch doesn't work if you slip it too much, and that's why I yielded a higher 60'. Perhaps a mystery to some, yet blantantly obvious to others.

Actually, it tapers about 4 psi from the spike...so that would be 18 PSI steady after a 22 PSI spike. Is a boost controller really going to make such a big difference?

I don't need your approval for a reason not to run a test pipe. Every cat-less car I've seen SMELLS. I use my Evo often for driving around, NOT just at the track. Launching from 4K RPM isn't lame if you are trying to get a feel for the car and preserve the stock clutch. Also, if car needs such a hard launch to hit 12s then in my book it really isn't that fast...I'd rather be able to cut 12s with a 2.0-2.2 easy launch.

If feedback was all you wanted to provide, it could have been done in 2-4 short sentences. Considering that I was able to cut a 13.1 from a car that was otherwise putting down close to stock levels of power, maybe 5-10 more HP From the exhaust but still stock boost level, I'd say those runs were dead on. The only reason I would have expected faster times is that I thought the flash would increase my boost - but the flash does not do that, it just allows you to run higher boost than stock.

A bad run would have been high 13s, low 14s or worse. FYI the launch has little to do with the trap speed. You'd think that 5+ years exp with any car would have lent you that tidbit of knowledge.

As for my car leaking boost...is it normal for 2 month old cars from Mitsu to leak boost? If so that's pretty shoddy workmanship...

 

Your 60' could definitely improve but maybe you are just shifting slow but your mph are very low for the mods that you have...how were your shifts?
