What would be the best turbo setup needed to get the rallyart to 500whp + and im getting the ssp clutch kit with fan and rad just need info on turbo and engine parts i got the intercooler thats good for 700hp. I was thinking of FP black but i been told it takes a bit to spool up. I want be doing 1/4m racing just track. oh and i want the ball bearing turbos. Any helpful info is appreciated.

thanks

 

i dont think there is any ralliarts putting out that kind of power since the tranny slips after 350whp-ish.

 

Talk to Bryan "razorlab" he has around 400 hp in his Ralliart I think it could be done with time Money and the right parts / tune.

 

Plan in spending ~$7-8K, maybe as much as 10. You will need to do a "moderate" engine build if this a DD you want to last more than 10K miles . There are an increasing number of MR's hitting 500whp, look in the Evo X Dyno Results for an idea of what all is needed. But be prepared for some serious coin to reinforce MOST everything. Good luck, I look forward to seeing more people pushing the RA. If I had the $$$$$ I'd be right there with you

 

Stick to 300whp and spend the rest on track events, the car will last longer.

 

Yeah 300whp/wtq is a good number to be at. Anything over 400 you should just get an evo gsr and work with a better foundation

 

Completely agree, If you wanted a 500+ RA, to spend the money getting there, you might as well have gotten the Evo or even a better car, oh wait what??

 

You don't need a turbo, all you need is a dynodynamics operator willing to type "x 2.5" that should get you a plot with over 500whp and about 600 ft/lb torque

 

Id have to agree with these guys..if you want that much power..get an evo, I think youll be happy to upgrade anywats..

 

500whp is A LOT for even an Evo. so many people don't realize how much 500whp actually is.

i just don't think the OP is being realistic, considering these types of numbers takes way more research to hit

 

Maybe he is talking crank numbers? Or maybe wants to be a real Evo killer?

But I agree with most people, that you should should have probably gone with an Evo instead. However, go into the Evo sub forums and basically find a turbo that suits your needs. There are quite a few of them out there. Talk to Cam at Lightspeed(Red Deer), I believe that they have had some experience with high hp/tq Evos.

 

I heard a good piece of advice from a local guy who has been building cars and trucks for a long time, imports and domestics. The idea is simple, most manufacturers build their cars using components designed to handle ~50-100% more power than what came stock. Obviously, this doesn't apply to everything, and is not a rule by any means. However, its works as a great guideline.
For example, the SST needs attention once the torque numbers cross ~350wtq. This is close to 50% more than stock. 500whp is over 100% more than a stock MR, which means that to hit this hp target with any kind of reliability, EVERY component in the drivetrain should be treated as a possible weak point. Again, this is not to say that you should expect your car to grenade if you hit the target hp, I'm just saying to not be surprised if something breaks.
If you follow these guidelines, it comes down to two options.

First: You build up the car and address all issues that may present itself down the road, and you have a car that can reliably handle the power you're putting down. If you build the power and try to keep things cheap, the car eventually blows up. Ask anyone who's done this kind of thing before.

Second: You realize you don't want to spend the money required to properly hit your current target, so you set a new hp target that is both affordable and reliable.

I fall into option 2. I'd love to have a 500whp car, and to build one I'd start on a proper platform, which would be an Evo. I don't have an Evo, and furthermore, if I owned an Evo, I wouldn't want to spend the amount of money that would be required to make my car that powerful. I own a RA, but I want to keep my modding costs fairly low, and stay on the stock turbo. Therefore, I've set my hp target for my Ralliart to about 270whp.

500whp on a Ralliart would require a turbo upgrade, large FMIC and piping, turbo back exhaust incl. downpipe, equal length turbo manifold, dyno tune, SST cooler upgrade, fuel system upgrade, cams. You can eliminate some of this if you decide to run on race gas.

500whp reliably on a Ralliart requires the above, plus a full SST upgrade from SSP, and an AMS or Cosworth built block and CNC head.

500whp safely and reliably on a Ralliart requires the above, plus a big brake upgrade, sway bars, chassis stiffening braces, engine mounts, coilovers, a roll cage with harnesses, the list goes on.

 

guys thanks for all the inputs, I know that my goal is up there but i know i can get it there. I ask for what kind of turbo upgrade would be the best to get to reach the goal and not if I should do that or not, I love making something out of nothing its the intercooler and piping is changed with 700 hp intercooler and piping AMS short ram intake i changed the suspension and it is really stiff now its fun in the corners i already got almost $10 000 in to it so money is not a problem it took me 2 years to get that but its done.
SSP 600hp clutch kit with the cooling system is next and BBK ( not sure on which one to get ) it wont be this summer may be over winter or next summer. The car is a project it will take time and money.
I thought engine is 100% the same as Evo X with little change to it, it should be able to push 500whp no problem. The only problem that i might have is AWD system when it transfers power when cornering. AWD is not built for that much power Evo X is as I been told.

thanks for the inputs
