i have first hand experience with boost.... building a kit, driving it, and blowing it up
first thing u have to know, do not think outside of the realm. u may not think what u have is fast enough for u, but don't compensate for that by upping the boost ( unless your car has forged internals, ours do not)
2nd, it's not as easy as throwing a turbo on a car and calling it a day. I know because 1 they never made a kit for my vehicle when I was boosted, so I had to fabricate my own kit( with the help of my friends welder) the size of the turbo must be spec'd out, when u want boost to hit, when u want to reach full boost are all factors. I have a book in which I have read MANY MANY times, which will help determine the CORRECT size of the turbo
3rd, fuel. Fuel is your friend with a turbo/boosted car. the perfect air/fuel ratio for a boosted car is anywhere from 11.5-11.8 under full load (boost) as for a naturally aspirated car 12.7 is perfect under full load. ( the lower the numbers the richer the mixture of air/fuel, hence the name AIR to FUEL). an improperly equipped fuel system on a boosted car can cause many problems even death of the engine. boosted cars, do not like a lean mixture at all. So fuel injectors are a must, a fuel pump is a must, and a fuel pressure regulator is a highly recommended.
4th, tuning. a car will run boosted untuned, but DEFINITELY not recommended. A proper tune will ensure correct air/fuel management,timing a whole bunch of other crap. and will also yield more horsepower. and yes, john doe can make 300whp, while joe smith can make 286whp. but whos to say who's is safer? timing has alot to do with tuning as well.
5th, research. ALOT, do alot of research and do ur homework
6th, maintenance. There is alot more upkeep on a boosted vehicle (more so a turbo then supercharger) due to more wear and tear on engine internals. Do your regular scheduled oil changes, and inspect turbo components fairly often to ensure less headaches down the road.
Boost is amazing. It is like sex, maybe even better. but if you do not know what u r doing, u can screw up big time!
if anyone has any questions or anything about turbos or spec'ing a turbo, just hit me up, ill be glad to help u out as best as i can
i have both ingalls and the eibach/spc. I like the ingalls more though, cause of the wide range of adjustment. The camber adjustment on the ingalls is almost double that of the eibach/spc. and also the eibach/spc doesn't have any toe adjustment.
i had my flex pipe replaced with a better quality one. It cost me $75 for parts and labor. Granted my flex pipe wasn't cracked or anything, but it did give off a strange whistle noise. Once it was replaced no more strange noises
i have underdrive pulleys on my car as well. They've been on for about a year now, and I have not had any problems what so ever, although I really should do an oil analysis test.
I don't beleive our pulleys have a damper on them. Last time I looked at it, all it had was a hard plastic/rubber ring seperating the body from the ribs.. almost like 2 different pieces, just glued on to each other, with like a polyurethane type of substance. Reason why I say so is because on my buddys old lexus I had to change the crank pulley, cause it literally came apart in two pieces. The ring that has the ribs on it, came off in a ring right where it was held on. Granted yes it is a lexus, but it had the same style setup as our cars.
