Dang should of learned stick I guess ... Here is a kind of random question in fact entirely off topic and you guys might not know a friend wanted me to ask hes got a Integra no turbo and he joined a forum for Integra's but apparently there not awfully helpful he has a exhaust on his car i think its 2.5 inch piping and like a 3 or 4 inch tip not sure exactly but some one had mentioned to him that he opened his exhaust up to much due to him not having a turbo which I guess would result in losing power if that were true because of no back pressure anyone have any idea of if that is accurate?

His car is automatic too btw and more specific specs if need be, 1998 integra GS hes got intake, exhaust with the inch specifications i mentioned above and I believe spark plugs and pcv valve

Show this to your friend:CobbTuning.com - Exhaust Design, it mentiones non-turbo'd applications also. Might help do some explaining for him.

With all due respect, I think you're dad is thinking of muscle cars with high rpm torque converters in their trannys.

It is generally not wise to rev the engine while holding the brake (on an auto tranny), it induces extra strain/wear on drivetrain components over time

Yeah this could be possible as when he was a kid and into cars they were all old school big block v8 chevelles and what ever so yah that could be a possibility.

Also thank you for that link newtothegame I will be sure to show it to him.

Perhaps though I guess I should make my question a little clear say one races like once every few months at like a maximum and in those races one holds the break down would this increase ones performance and not really have a huge down side to the transmission since its being done on a rare occasion?

Yeah I know its not good I was used to a Camaro when I was doing that crap. They can handle the abuse alot better than a Wrx. I am not familiar with the auto in a Wrx because it wasn't even an option when I bought mine.

Dream, your friend has a small displacement normally aspirated car. This is different than your car. Car's can loose a fair bit of power from not having enough back pressure but this is much more rare on a turbo. The turbo itself creates a large amount of backpressure which is usually more than sufficient for the motor. As for your friend, I would think that 2.5" would not be that big a problem but then again, I'm not a honda guy. If he's still got his stock piping, he could try that?

Dream, there's this thing called a high stall torque converter you can use with an automatic (they even sell em for your car). This is what enables cars to rev from a stop with an auto. This is what your dad is probably assuming is in your car (which it does not have).

Yeah he was actually mentioning that to me today when I was talking to him about it in more depth he was saying that if I only revved it up to somethin small like 1000 rpms it wouldn't do damage to the trans jus wear the breaks a bit...So how much does a high stall torque converter cost??

I will admit that I just skimmed through this but... I didn't see the real issue discussed.. Depending on the race, which drag keeps comming up the choice is different. For anything but drag an stick is the way to go simply becuase you can keep the engine in the power band at all time (when possible). However for drag an automatic is a better choice when your compairing apples to apples.. Most of the time the automatics are NOT geared the same which is why the sticks will turn faster 1/4 mile times in the Subaru and Celica (2000 GTS) which I also have expierience with.. If both transmission were geared the same the automatic would turn much more consistant times which will win at the tree. It's not always about being the fastest more so who is more consistant and can hit their ETs.. However I run a stick and will always run a stick becuase it puts more on the driver and is simply more fun..

As for Netural drops, unless your 16 in your first POS car don't due this PERIOD..

As for break revs, this is also not something that I suggest.. It's one thing to do a break stand in a RWD, but it's another to heat up the transmission trying to push power to 4 locked wheels.. Just not an idea if you want your cars transmission to last...

Yeah Neutral drop I deff am not looking to do because I've always been told thats terrible for the car I just wasn't sure if "break revs" were so bad for the car as well.

Ok, end of story. Brake reving will put a ton of stress on the transmission and drivetrain. Let alone stress the brakes. Because your awd and you don't have a high stall torque convertor. Simply the fact that your awd, the following will happen. You'll have no tire spin and all the added stress will stay in the drivetrain. Basically pre/over stressing everything from the tranny the whole way out to your tires. The tires won't be affected, but everything else in between is. You can do it and get away with it for a period of time. But, it will come back to bite you in the ass eventually. Next subject, please!!!
