Will I really get 59 more ponies from RB exhaust?
http://www.racingbeat.com/FRmazda2.htm
Racing beat has a claim that a 59 horsepower increase with there complete turbo 2 exhaust system on my s4 t2. Now i know that rotaries react really well to fresh air, but is the increase really that big? Has anyone had any expirience with this? if so how big was the performance boost? Thanks. Sergei The Saint.
P.S. Also does anyone know of a good place to buy performance bushings for an s4 t2? Thanks

You'll blow motor if you boost past 10 psi on a S5 or hit fuel cut on the S4. You'll also get louder note too. i would really get a FCD with that. and maybe a bigger fuel pump. Leave the stock intake. Fuel is probably the most overlooked item. Funny thing is that without it, you can't make power.

59 HP would have also been acheived on a stock FC which was in PERFECT running condition (ie: excellent compression, new spark plugs, newish condition exhaust, etc)
If you put this system on the average used FC which is running 100% properly in stock form, I would estimate that you can safely get a 30-40 rwhp increase.

We just put it on a friends car. He also went with GSL-SE injectors and Walbro pump at the time and FCD. Runs awesome and is now boosting 10psi in all gears, I think it would be hard to dispute RB's claim.

I had an '87 TII, I now have a totally stock '89. The '87 had a 3 inch downpipe, main cat replacement pipe, and some decent mufflers. Otherwise, the '87 was stock. The 'ol butt dyno says that the '87 was faster than the '89. I'd say the exhaust gave a good 30-40 hp. That's compared to a car that still has the stock main and pre-cats.

The '87 had a totally stock intake and it never hit fuel cut. It was a great running car.

an averrage used FC would gain more from the exhuast then a brand new one....
also does it say "peak hp" ?? can't remember. it probably adds 59hp at like 4000rpm or something

Its only if you don't have an FCD that it is a problem.

LOL.... FCD does NOT make it safe to boost higher... it just allows you too. what is making it ok for him to boost past 10 is his 720cc secondarys.

No way in hell the average used FC makes more power than a brand new (but broken in) FC.

just because it adding 59 doesn't mean its 182 + 59. it's whatever they had before they put it on + 59.
