Come on, man, do you really not understand this most basic of concepts? You have a set boost right now. To change this set boost, you install an MBC, then drive the car to see where you boost is. If it's 15psi, then you turn it up and go check again. If it's 18psi, then you turn it up some more and try again. When it gets to 22-23psi, then you leave it!! That's all. I never said "you turn the know until you hit the boost." This is not some nitrous button thing where you're driving along then suddenly you "TURN THE KNOB" and go warp speed. Good Lord have mercy...

when can/should you use it? You use it every time you get in the car, because it's installed and sits there.

 

Hey warr i think this guy is pullin your chain...

 

yea its "knob" not "know"...anyways COOL thanks Warr.

 

Lol!

 

Warr, I know he's your sponsor and everything but you need to relax.

I dont use buschur parts after I've seen several people experience problems with them. These were mainly fit and finish issues rather than performance related ones but for my money that crap doesnt fly. I'd rather spend a little bit more and get a better product. I also think there are better ECU tuning options than the dynoflash reflashes they use, but thats just my .02.

I'm not knocking Buschur as he as already proven his company and his cars many times, they definitely know their shyt on the 4g63, no question. They build great engines, and design a lot of good products but I'd prefer to go a different route if it were my car being modded.

 

You can prefer all you want, but you said Buschur's products don't cut it. That was a blatant, unfounded attack. Why would I relax when you say such an untrue and ridiculous statement? Also, how can you "think" there are better ECU tuning options. You can have a preference, but that doesn't make them better. There are thousands of Dynoflashed cars and a bunch are high-11/low-12s on the stock turbo with basic mods. I'd say his tuning is quite good, and for $1270, the power gains, drivability, and reliability are amazing. Buy whatever you want, but don't go around telling people in a Buscur-related thread that Buschur products "don't cut it" or that the guy should drive to TurboTrix and pay $650 alone for his flash while ignoring the fact he was asking about getting a stg 1 package, and they don't even sell a stage 1 kit.

It's one thing to have a preference and make suggestions - it's another to be blatantly and obviously anti-Buschur/Dynoflash. Take it elsewhere, please.

 

Having things that work together is always best, since they have been tuned the to work in conjunction with each other

 

^^Man you really over analyzed my utterly simple post and completely misunderstood what I was saying

I guess I should have been more specfic and expanded on what I was trying to say. For ME personally they dont cut it, for a lot of happy people they definitely cut it(refer to previous post). Also, I suggested turbotrix for the tuning because he's right there in jersey, so a custom dyno tune would be a better option compared to a mail in tune, even though its more money. Than he can buy a turboback exhaust and have the stg. 1 setup. A few hundred more dollars yes, but well worth it.

I have my own reservations in regards to dynoflash tuning and SOME buschur parts based on first hand experience on more than one occasion. This industry isnt perfect and sometimes products and tuning services dont work/perform/fit they way they should regardless of who it is or which company, so it is in no way a personal attack, jesus get off their nuts and your soapbox please.

 

When the taper is removed, the chance of detonation is greatly increased at higher RPM. Is that right? If so, should one be concerned relative to the engine's longevity? Meaning, how is that chance diminished, if at all. TIA

 

Well, yeah, the "chance" is increased, I guess, but this is what we do on every Evo. The stock tune is very rich and goes increasingly rich at higher rpm, so even removing some of the taper on the stock tune is safe. Then, you get tuned anyway to ensure the boost, AFR, and timing are safe and do not lend themselves to detonation. Engine longevity is always in question when modding and increasing boost, but there's plenty of Evos with high mileage on increased boost. We're not talking crazy boost - just a few psi over stock. We have one in DC who has hit 120k+ with all the basic bolt-ons and about 330whp.

 

I appreciate the reply. Do you think it makes sense to get a tune that doesn't remove the taper, along with the boost not being increased relative to stock? Are there gains to be had with such a configuration?

 

No, it doesn't make much sense to get tuned or mod yet leave the boost stock. Is there a reason you'd want to do that? We make a lot of power from raising boost as well as removing taper. You don't want it to drop to 16psi forever. On a IX, you will still gain some good power with a tune that doesn't affect boost - moreso than on an VIII - but it won't be as much as it could and should be.

Are you perhaps asking in terms of SCCA Solo II STU rules?

 

^ Well said, and certainly true.

 

I'm asking for two reasons:

1. I'm a chickensh!t when it comes to turbochargers and upping the boost is the pinnacle of my fear.

2. I'm curious, as I'm trying to get a better understanding of the Evo. I don't know if I'll ever mod the car, but reading the board has piqued my interest.

In terms of the SCCA, I'm sorry to say that I'm not good enough of a pilot to compete in the Evo, plus I'd hate to lose the warranty. My GTI is better suited to my abilities and it's a car that I can handle with some confidence.

I have another question, if you don't mind. According by the stock boost gauge, my motor peaks at ~1.25bar, which is ~18 PSI. Am I correct in assuming that's a bit low? Would hot/humid weather be responsible for the lower boost? Thanks again!

 

Hot weather can affect it and make it lower, but it's also possible that either boost gauge is off or your IX just doesn't boost as much from the factory. It also depends on what gear you're talking about. It will show less peak boost in 1st gear than it will in 5th gear. More load means more boost, but yeah, if you only peak at 1.25 bar in 3rd gear, that's a bit low, since stock is 20.3psi (~1.4bar).

1) No reason to be. This is an Evo man...I don't think you know what you got - you basically have a supercar. Raising the boost is not a problem at all. You can run 22-23psi all day on that IX on 93oct. You can run up to 28-30psi on race gas or alky if you really want to. The 4g63 engine is a cast iron block with a forged crank and forged rods - it is made to boost.

2) Hey, just a basic stg1 package for very little money will put a huge grin on your face. A 60-70whp gain is unbelievable - gives quite a rush.
