looking to build a 450-500 bhp lump what will i need ?????

 

money and loads of it maybe winning the lotto will help lol

ring some people up have a word with them im sure they'll advise you

What are you going to use it for? trackdays? I think its way too powerful for our roads tbh.

 

thanks

 

yea the road and the odd track day here and there

 

If you were keen on doing it on a budget your best bet would be a strong 2.5 from the USA, some sti heads (obviously depends on what your starting with) a 6 speed from a new age (i'd go for a UK 6 speed so you have some decent M'way ratio's).

Also a suitable turbo which will depend on budget, MD321T, SC45/SC50, FPGreen/Red ect.

Thats really the main bits taken care of, other than that you'll need a FMIC, injectors, 3" exhaust, good idea to have a parallel fuel rail, maybe some adjustable cam pulleys (possibly overkill but if your going to do it then I always like to do it as well as possible) headers, uppipe. You could also add some methanol/water injection to it if you were really keen. There are lots of other little bits and bobs to add in but nothing major.

I think you'd get it all done for under £10k if you sourced as much as possible from the states and had someone reasonably priced to do the work for you.

I'll get round to doing one myself one day but for now all of the money I was going to use for the subaru build has gone to a shiney new toy.

try neil at slowboy-racing.co.uk he is never short on options and ideas

what area you in?

 

<<<<<<<see here

 

Don't scoobyclinic do a package for around £9k or something giving 450bhp?

 

YEP The SC450

Scooby Clinic | The UK's Largest Independent Subaru Specialists | 01246 590 807 - Chesterfield S42 6QX

my choice would be a 2.2.... made into a 2.33

 

Im having my SC500 built by scoobyclinic and they start it next week going for the 2.33 close deck block and will be ready for shootout in may Garrett GT30R turbo 550bhp turbo I think

 

thanks very much for the advice guys and ill keep you posted

 

yup, im going down same route next year if all financials go as planned

 

IMO anything over 450bhp is a waste for road use only (even 450bhp is borderline), as you will never be able to exploit it's full use.

If you intend in using this kind of conversion on track, imo even if it is once, you will have to get a number of other things uprated other than an engine sorted.

If your on a tight/low budget don't bother imo.

 

confused here, thought it was torque that was problem? if not surely over 450 depends on which scoob you drive? classic, jdm or overweight uk? 500 in a classic and 500 in a uk newage must be night and day due to weight.

 

Black Newage,
Both torque and power go hand in hand normally. Maybe not to the same level, but if you are talking a 2.33 or 2.5 it certainly will.

450bhp in a sorted Newage should be just as good as a Classic, if not better.... a newage has a much better chassis (if it's virtually standard, i.e. no strengthening) so you should be able to exploit the power better. It's not all about the added weight that a Newage may have or straight line acceleration.

Regardless of weight differences a true 450bhp Scoob is plenty for the road as most people can not even exploit a standard Scoob, let alone one with circa 180 more horses.

If you want to be able to brag how fast/quick you can go in a straight line fair enough..... if you want to introduce some bends then you will have a different scenario.

Have you driven a 450bhp Classic or Newage... properly (genuine question)?

 

No but I hope to get somewhere close to 400 bhp soon...
Roll on Blyton on August 16th.

I always remember being told a story by Richard Bulmer.

Customer:"I want 500bhp"
Richard:"Ok.... you ever driven a 500bhp car?"
Customer:"Nope"
Richard:"I can take you out in my demo car (Spec C Newage) to give you an indication"
Customer:"Awesome"

After demo drive

Customer:"That is exactly what I want"
Richard:"Ok.... you do realise that was only around 420bhp"

 

I was going to say, 400hp is a lot of power. If your using it on twisty stuff, its probably too much for most, if your using it in a straight line only, then it will make you smile but you do want more but you just end up doing silly speeds on seconds.

400hp is cheaper and easily plenty of power unless you've properly mastered that kinda power in the twisties.

Dont think I'll be doind anything else as mines easy quick enough for what I use it for.

 

Agreed I have 440bhp in classic at the moment and it is get to silly speeds in the blink of an eye.
To put your foot down you certainly have to be on the ball and fully concentrated as you catch other cars in no time. In the wet it will light up all 4 wheels in 2nd gear no problem, so much so that I usually drive it on the lower boost setting wet or dry.

thanks for explanation no is the answer to the 450 question mines bhp427 so a little way to go, have been in a passenger in a 487 bhp newage and 500 classic both driven by rcm, again night and day, now if i can ponse a passenger ride in martys 540 p1

 

Power to weight does play an important part..... granted, but I still think that a sorted Newage at a similar power level should be quicker in the real world road use. Competition is totally different as it all helps and it is what ever it takes to win..... even though I do have more respect for the companies that do this the harder way by using later shells etc, as that highlights a bigger achievement in my eyes (not taking anything away from the people that use the lighter cars of course).

Power to weight of my Newage compared to a Classic is less of an issue than a normal STi though.

My Spec C (as it was before the interior went back in) - 1340kg's
Classic - 1235kg's

At 500bhp, BHP per ton:

My Spec C - 373bhp
Classic - 405bhp

Neither hear nor there.... and for the advantages my chassis give me, I will accept the 30bhp per ton defecit.

 

your car must be mental to drive with that power and weight

 

Not really. Although Shaun thinks it's the dogs dick.

 

Coming from one of the "dogs dick" 's that built it for me!

Fuzz actually said to me on Saturday that when he drove it (when he was working on it last year), he was expecting it to be an animal (based on the torque being acheived and the fact that the RR was struggling to cope with how the torque came in with grip)....... unfortunately it just gripped and went with no drama's. Perhaps that had something to do with the fact that he was used to the handling characteristics of his previous classic.

The feeling is one thing, whilst the speedo will tell you something entirely different.

I was testing the other week at a closed venue and whilst whizzing past 160mph (true speed) the passenger at the time couldnt believe it was going that quick, as he said "It feels like we are only doing 100mph as there is no drama and the engine doesnt even sound like it is being pushed".

500+ of each is a lot of power, so don't over estimate what you really need.

 

 

Its funny if you go through the gradual modification route, 450-500bhp in a classic doesnt feel like its enough in the end
If your new to the power, 400bhp with a smaller Turbo feels more than rapid for the road, but is bloody useless in the summer on Track when it runs out of puff
Funnily when I went from race fuel on the 20g to using a mixture of all sorts on the 321S even though the car had about 50bhp when it went over 470bhp my wife complained that the car was too slow because she wasnt driving it at speeds much above 70mph.....

I love to be able to floor my car occassionally on the motorway..... Road use is sometimes interesting (but always potentially dangerous) so you can exploit, but if you live anywhere near London like I do, the roads are such that you can just forgot any real fun except on the Track (though really for safety that what such a level of power should be used for).
