Hey I read this in another post and was wondering if this is true? I have thought about this and this could work for some cars, larger/more expensive doesnt mean better.

"One discovery : on certain cars, using a smaller (and cheaper) exhaust and filter system kit along with a latger turbo gives you mosre HP than a larger kit."
 
i've noticed.
lots of high turbo cars produce more bhp with sports mufflers than racing mufflers (with the stock turbo).
 
You know I dont actually think ive ever used any of the sports or semi-racing equipment in GT3. I just went straight to full racing, and im not going to bother faffing around with it just to see if it gives me more BHP. Now if youll excuse me, im off to play GT2. :p
 
Somehow I am able to imagine that the graphics are like GT3`s (I have a great imagination :) ) I also have a steering wheel for my PSOne, so it makes it more fun then using the pad. I dont have a wheel for my ps2.
 
i want a wheel.....maybe i should look around for a cheaper used Logitech one....
why the heck did they have to make it $100.......stupid logitech.....i'm not fricken rich.....i just always have $80 in my wallet.....lol (i'm sort of a loaded high skool freshman....) $20 is usually used for buying food at skool tho... $3 a meal... then $1 for a drink....
 
I can use the PSone wheel with it on my lap. But because the Logitec wheel has force feedback I would need to mount it on something, which is impossible in any room of my house. So i never bothered with a PS2 wheel.
 
lol race
and i think i know why sports mufflers can produce more HP than Racing Mufflers..... ykno how a racing muffler has a hugeass end right? well.. sports muffflers have smaller ends.... and that end determines how much *push* ur engine has against it... if the muffler has just the right amount of push... ur engine will produce @ its peak efficientcy..... but if ur muffler is too big..... ur engine will not produce alot of HP
think about it... look @ the civics around you.. .ppl giv em bigass mufllers......
when they do that... you always hear their engine go.. "vroom" but the car don't move.. why? cuz thers not nuff push against the engine


this is just stuff i read when i was bored in car magz.. iono if its true.. but it sure sounds good
 
and.. zerp is right... back pressure is really important.... its like... firing... a cannon.. if you don't build nuff pressure.. it won't go far... just like the engine... if you don't have nuff back pressure... theres nothing for the engine to push against... so you have like.. really.. loose.. power... i think i'm just..... not makin sense now so i'll stop
 
Back Pressure can also be a bad thing in high doses...Luckily for us, PD didn't include the physics of over pressure in the downpipe to slow down a turbine....
 
Well if you have a restrictive downpipe exhaust gases from the turbo will get caught up en route to the exhaust. Bigger turbos have bigger exaust outlets so if you don't have have pipe with more flow to compensate, gases build up and the spool rate of your turbo will be slowed.
 
so if you want a big exhaust.. get a bigger engine first?
and i was just curious about this.. but what if you had a exhaust that was too small... would the gases force its way out?
 
Well excess gases would move back into your turbo and damage performance and/or apparatus. When working with larger turbos you need proper flow in many aspects, both intakes and out-takes. Say if you're working with a turbo like the "Stage 4" in caliber, say a T-88H, you need proper intercooling to decrease lag and also proper piping for exaust, like 3"-4" to manage the increased air going out as well as in.
 
skar... i highly doubt that in real life you'll have a car with a stage 4 turbo that adds so much hp.....
unless ur talkin bout gt :D

and midus, whats a t-88h? is it an engine?
 
A T-88H is a medium/large sized turbo made by Greddy/Trust. It is a turbo itself not an engine. The T-88H is said to support up to 1000hp with certain mods. There are actually bigger turbos out there too...A lot of people use large, single turbos because they have massive high end whereas a twin turbo set up is usually run with two sequential twins for less lag and much more response. Some of the HP numbers that are achievable are staggering. Fuel also has a major role in power numbers. Pump gas, or your daily driver gas (93 octane) has much less power than other fuels. With a change to 101 octane, or "racing fuel" you can see up to a 50hp gain. Then you get into stuff like methynol, nitro methane, alcohol, etc which can boost your power into high, high numbers far beyond 1000hp. Keep in mind though using advanced fuels is not for a daily driver engine!

Happy Thanksgiving, everyone.
