hey guys whays up?? iv only posted here a couple times and havnt in a while, because i am trying to decide on a car to build up still. but i find my self back to leaning towrds the fd, esspecially since a-spec tuning in a few minutes away and i hear they are real good.



so this is my question, iv decided my goal for the car being that it weighs so little is i would like 400-500hp at the crank. do you think that could be done with a turbo thatll hit full boost around 3000rpm???? i want a straight up bad *** street car, thats why low end is so important.



thanks

well i see that the people that viewed my post are to good to answer it and help me out. iv never owned a turbo car so even though this question might be stupid to you, not everyone is blessed with the knowledge of knowing how a 400-500hp rotary will perform.



if there is anyone that still realises the whole purpose of forums and wants to be cool and help me out, id appreciate it.

I'm also a newb, but I'll throw out a no.

The single to run that kind of power would not spool that fast to full boost.

Talk to Sean, I'm sure he'll give you a ride in his car so you could feel what 500 at the crank feels like and where the boost comes on. You're not gonna see it at 3K, that's not gonna happen, full boost would come up a bit later but would pull till redline from a decent size turbine.

actually to anyone that reads my original post. i said 400-500hp at the crank but i dont even need 500. id just like 400-450hp at the crank.



that bring me to something i forgot about. ignore the original post if you want but a shop i talked to told me this and if you could brake it down that would help.



they said with their turbo 385-395rwhp could be made with full boost(15psi) by 300-3100rpm in third gear. now thats cool, that means boost will be there fast in 3rd gear but could you tell me what kind of response that would have in first????

Quit worring about the numbers so much. You soulnd like someone has been reading the internet to long. Go get a ride in a fd from Aspec. You said they are close. I am sure that they would be more than happy to give you a ride and then you can see for yourself how hard a fd pulls under boost at 3k. I am sure it will be faster than you expect it to be.



Good luck.

yea they are close and that sounds like a good idea. its the best way to know for sure. i really want a turbo car but i always hear, "low end sucks" you always got to keep revs high to get n e power" but your right, those people probly dont know what they are talking about. i need to see for my self





thanks

low end doesnt suck on all turbo car's, slap whoever told you that.. i have enough power down low to spin my tire's for 50 feet before i hook up, i've practicly gotta start out in low boost to get any traction, and my boost comes on almost instantly when i floor it any time above 2.5K. and my turbo spools completely by about 3.1K all the way to 17 PSI.. im pushin about 310 whp on my car and it's my daily driver, you wont really need much more then that imo unless your gonna make it a part or full time drag car.. i've never owned a turbo rotary, but i've owned several piston turbo car's..

like ive read before



"if you have turbo lag, youre in the wrong gear"



That being said how much money you have set aside to build a 400-450hp rotary motor? I'll tell you this much im building a T78 terror, aiming for 550hp at 20psi. Its come down to, basically, em replacing everything just so there is some reliability in the equation. So far im looking at around 13-15k...and thats with me doing all the labor. But hey better to build it right the first time, no?

i agree but its so flucking expensive to go through with



im aiming for 400 rwhp eventually, before i pulled my motor i was stuck in 300's



when u say 400-450 at the crank what kind of drivetrain loss are you anticipating. 15% would be 340-382.5 or somtehing like that at the wheels which u can do easily with stock turbos all the bolt ons and maybe a street port.



i was at 320 (368 at the crank if u use the 15% rot) with a stock intercooler at 12lbs, with no turbo lag.



**that being said im still looking to go single down the line and ditch my days of no turbo lag for a bit more power and a lot less vacuum lines
