Got the 1/4 mile bug after going to Ten of the Best this weekend and wondered what it takes to get an Impreza into the low 11s, high 10's?

I know everyone is going to say "a lot of ££" but thats not what i'm after. What sort of spec, bhp, weight etc would get you a reliable 10 second Impreza?

Looking at some of the cars in the Fastest Subarus section I can see that 400+ bhp is a starting point for 11's so then i'm hunching that weight reduction, RA gearbox etc is another way forward. Can you do low 11's with a 2.0 or would a 2.3/2.5 be a better bet?

Must be other people out there wondering the same thing so feel free to post up if you're "in the know"

 

I'm not really in the know, but it you would need 600+bhp and some weight reduction in a classic to achieve 10 secs IMO

 

600+ will get you low 10's from what i've read, 450+ low 11's

 

Andy.F did an 11 sec dead in his newage with a 321T, I think it was about 480(ish).

 

A/ Book car in with Enginetuner
B/ Pay bill and collect car
C/ Go to drag strip and run 10's.

Or..

Classic fully trimmed.
2.1 stroker.
S206 turbo running race fuel.
10.8/134 mph.

 

How bigs the bill ?

 

that was on a uk gear box as well wasnt it Alan?

 

Standard gearbox/diffs etc?

 

See my project thread.

10.9 secs with an awful lot more to come.

Full blown DIY project documented here.

didnt bob @ aztec run an 11 with relativly low bhp and a ppg box? just goes to show...

 

Think it was 11.7 with 340bhp

 

Yes it was, we managed a couple of years on it. Sooner or later we knew it would break of course! We've gone for a PPG now.

 

You might not be after that ("a lot of ££"), but that is what it takes and its almost impossible to get a reliable 10 second impreza. Eventually, pushing a car that hard something will go bang.

Dont jump into it just because you've had a nice weekend at TOTB and it looks like fun. Trust me, if you do you'll regret it.

Listen to people who have been there, seen it, done it. These cars are expensive and there is no way round it. If you take a month/two and have a look around, read up on these cars project threads, talk to people who know what it takes etc etc and still want to do it then go for it.

The fact you need to ask (And honestly, no disrespect intended) what it takes, to me means this is a bit of a knee jerk reaction to a great weekend, and we all understand that. Its probably what got a lot of us interested. Just some friendly advice mate.

Spec wise, Mikee is running a 2.1 stroker & billet GT30 and has managed 9.66 1/4. But he is an experienced pilot and the car itself has had some serious R&D done to it. It weighs less than 1000kg.

Many others are using 2.35's with various turbo's, billet 35 being a favourite. These are doing 9 and 10 second 1/4's.

Thats not to say it cant be done on a budget because it can but you need to understand that even on a tight budget you'll be looking at between £15k - £25k depending on spec. If you cant do the work/build of the car yourself you can add a lot more on top of that in labour.

Building a car like these is a lobour of love but they can also be a real PITA. Nothing fits as most parts are aftermarket/specialised. Everything needs brakets/supports/parts fabricating to make them fit. And so on and so forth.

Plenty of helpful people around that will be willing to have a natter so I'd take advantage of that before you jump in.

Good luck whatever you decide.

Trust me buy a car thats all ready proven and built save £100000s

 

got funds?

do it.

great fun, learn all the way - and something yioull never forget - just dont bankrupt yourself - not worth that much

 

This man speaks from experience and I echo exactly what he said, its a roller coaster ride that sometimes you want to get off but cant....

 

+1
I got an RA with a good spec, added a MD321T and PPG and was getting 11.4's and with a better driver would have been faster

Total cost was under 10k


Dam i miss my RA

 

what car have you got? what times did you do. ET, 60ft and terminals?

 

Bigarf's blobeye is in the tens and runs 650 bhp...

dunx

P.S. A healthy Classic RA is a good starting point... IMHO !

 

I have a car thats over 600bhp and I still don't run a 10 second 1/4 as its not just the car its the driver as well. If you want a car for that power set aside a minimum of £20k or just buy one thats already done as that is the far cheaper option

 

Likewise shyte driver

 

some wise words from some experience there

 

I have an early classic that i bought for 6 grand 5 years ago i then spent about 10 grand doing bits and bobs to it, making it look how i wanted then stuff to the engine and ended up with about 330bhp then 3 months later then engine got very poorly, ended up not repairing it and its sat in the garage instead i bought one that had already had 10's of thousands chucked at it running 520bhp and done a 10.8 quarter. within a couple weeks the headers had blown but best part of a grand later we are back on the road. it is stupidly fast on the road i have never reved it over 6000 rpm because you don't need to(limit is over 8000). yes on 20quids worth fuel i got 30 miles but who cares its worth every penny hopefully get it on the track soon , but i only wish i had bought one in the first place that had the money thrown at it as long as it has the right bits on by the right company and engine tuner seem to know what they are doing....
you never know 9 grand might tempt me to part company with mine....... but i doubt it.. got a twited turbo set up to get yet o and a roll cage o and some fibre glass doors o and............its never ending

Or get on Whats happening with yours

 

I prefer to spectate these days, as Im a bit big and heavy for this drag racing malarky

 

 

I was just purely asking what the starting points would be and what the major components of building a sub 11 car would be as there must be quite a few people wondering the same thing.

I've got a 338bhp MY00 classic but its only got a VF35, full exhaust system, ecutek and walbro pump to get that.

I was just wondering if making an impreza substantially faster than a mildly tweeked one is a huge venture or something that can be done by mere mortals. I know everything costs money, but there must be things like weight saving etc which go towards achieving a better performing car.

I am new to Imprezas, only had mine 2 months but have already done the Nurburgring in it and i'd like to make it more track/sprint ready which is why I went to TOTB to see what was running and how they performed.

 

suspension i.e coilovers big fat brakes, theres 1000 if second hand, engine build 4 grand ish, from engine tuner, big fat turbo 1500, 800 if second hand, gear box 2500 for a six speed, injectors 300 ish for some laterall flowed phase 2 ones, fuel rail mods and fuel reg 300 quid may a touch more clutch for 500hp+ your need to spend a grand on that maybe a stand alone ecu 1000, headers 400, fmic 4000 and that for starters

 

im sure there is more then that as well

 

the classic is the most expensive car to tune. needforspeeduk has it about right cost wise. look at between 15 - 20K to do it properly. your weight saving will not be that much believe me i have tried. don't forget, the faster you get, some drag strip require you to have a cage, which put the weight saved back on again. as has been said, if you have deep pockets then go for it, but don't be chasing other people's big hp figure as there will always be someone with more money than you.

after a certain stage your car is no longer a road car or just becomes too fast for the road. think long and hard about what you want the car to do. you need to think about drag, sprint, hill climb or a combo of all three. setup and engines will be different in these cars and your choice of speciality will have different effects on your wallet. A track car will ultimately be cheaper than an out and out drag car.

Anyhoo you pays your money and takes your choice but most importantly enjoy the car. do it because it's what you want to do and not because you need to chase big hp figures.
