Just a LITTLE more power- --Need some simple advise P

[Manach]

About the RPM, 3300 for the 110-120 km/h is what I got. Might be more 3500 rpm though. At 140 km/h, I am at 4000 rpm.<P>So I would say for the rpm, you might be ok.<P>I have heard too a sound when I'm driving my car at 5000-6000 rpm in 3rd and 4th gear. I think this is my axles. I need to change them. There is no sound at those rpm when I'm in 1st or 2nd, so it might be the speed causing those sounds..<P>Hope it help you.

Ok guys im going to let you in a little secret for hp and tourqe. Its MAZDASPEED stickers, they add like 43 hp/ and 25tourqe. You cant go wrong there

Ladies, can we quit the bickering? 007sniper, you are wrong again, or you should rephrase your wording to make it more appropriate. Motor mounts don't give you HP! Period. They help you realize the power that you already have but has been wasted in the drivetrain loss. This is power lost due to the rocking back and forth of the motor. Jesse is correct in what he said. You are correct to a point but your thinking is off.<P>The part about the removal of the cat, once again is wrong. Removing the cat cuts down on back pressure which helps to increase flow. The only time that this would be a problem is on cars that have 2 O2 sensors, one of which is mounted behind the cat. In this cas it would cause problems but not catastrophic ones. Why do you think all big block guys run sans cat? More power. I don't have a cat on my car and it runs great. You can add back pressure depending on the muffler. One reason your pal may have said this is because in your area it is illegal and a shop can be find a large sum of money.<P>The part about hp gains and dyno tuning. You first said something about 240hp from dyno tuning and then you said in a later post about it being at the flywheel. Dyno tuning occurs at the wheels. The other thing had something to do with a 40% drivetrain loss, this figure is ridiculous. Most trannies only see a max of 20%.<P>Lastly, you could learn a lot from Jesse. He knows his stuff, especially suspension. Give him credit. I don't know why everyone fits like 12 year old girls. Just make sure your arguements are valid.

Jeremy,<P>I don't know why you get so bothered when things are pointed out to you. I agree that you gain HP to the wheels but it isn't like you are saying. The horsepower is already there you just loose it through the rocking of the motor. The less the motor moves the more power is put to the wheels because less power is lost through the rocking of the motor. You will gain more if you go to solid mounts too, although I don't advise it.<P>I wasn't bashing your comments on the dyno figures but think about it... if you tune on the dyno you aren't going to know the flywheel hp. You are making things more difficult to understand. If you said it would be realistic to achieve 200-275whp, factoring in a 20% drivetrain loss you would see 240+hp at the flywheel.<P>Stop the crying and take some constructive criticism. If you still don't believe the motor mount issue then go to <A HREF="http://www.egroups.com/messages/mazdamx-3owners" TARGET=_blank>http://www.egroups.com/messages/mazdamx-3owners</A> <BR>and see what they say.

Jeez, a guy leaves for a few days, and you guys go off :p <P>Anyway...<P>couple little things... dont trust everything that a salesman tells you, as they are trying to take your money. Derrick does know his stuff, but he is also gonna be VERY positive when it comes to if something helps out. Ben, the other CS lackie is a fool, and you should never listen to anything he says.<P><BR>flywheels, motormounts, lighter wheels, smaller diameter tires and the like DO NOT make your engine make any more power. <P>running a car sans cat will NEVER damage the engine. As stated, if there is an O2 sensor, you should probably leave it in there, just for ease of not worrying about fooling the 2nd sensor. <P>can someone tell me what stock turbo the B6T used?<P>Bullfrog (aka Gude) has a VERY BAD reputation of tuning anything OTHER THAN the D series honda engines. <P>Youre still not thinking of powerband. If an intake gives you 3hp and an exhaust gives you 5hp, it doesnt mean that you just got 8 hp.....they are at different RPM, and its usually very hard to improve oem parts throughout the ENTIRE range, from idle to redline.

Im telling you guys, MAZDASPEED stickers is where its at! They add crazy amounts of horsepower for a cheap price, 50hp for 36 dollars. Can't go wrong

The VJ-20 Hybrid I'm going with uses my stock IHI VJ-13 exhaust housing and Corksport replaces the center section & compressor w/ I believe a Garrett T3 Super 60 ball bearing which Derick @ Corksport told me 350HP @ 25psi at first but after talking to him a little more the other day he is saying 320HP because I have the 1.6 & not the 1.8. Didn't make much sense to me except I guess the since the 1.8 has a strong exhaust pressure it can turn it faster but I'm still not clear on why! Do you guys have any idea? The only other thing I thought of was maybe just because the 1.8 has larger displacement the turbo has more effect?<P>--------------------------<P>Jeremy Miller<BR>93 Mazda MX-3 RS-R </STRONG><HR></BLOCKQUOTE><P>Umm, i dont know a whole lot about how the hp figures for the B6 are in turbo form, but in NA applications, the B6 will usually get the same amount of horsepower, but less torque, simply due to the lack of displacement.
