Pretty cool vid below, lightening Type R at 4:25 mins and a 450bhp Newage STI struggling to 12.8 secs at 2:05 mins

It's gonna feel pretty awesome just passing mickywrx's 12.4!


Not much of a claim to fame, since your car is remapped and run more boost and power than me.

Same here.

People may say I'm full of shit, but, my car genuinely is what I say it is.

If I turn the boost up any more it fuel cuts, it's a standard V1 Impreza with decat exhaust, FMIC + IK, and a Z4 ECU.

It's never been mapped, I was talking to Pat socially about the Group N or A map that he has though. I want antilag.

Ask any mapper, and I mean any, if they say they have mapped my car you're talking to a liar. The only engine work, other than servicing that has been done on my car since I've owned it, was I had a rocker cover gasket replaced.

Obviously, I don't know if it had any engine work done on it in Japan. I'm the second UK owner, and it was imported by Vine Place. They tended to only import standard cars.

tbh I've blown several engines, and non due to running too lean from subtle mods!

Had a cambelt snap on an RST, had a spark plug fail at 120mph in a RS2000, got a full engine rebuild on an RST then blew the engine big time the next day flooring it, **** running it in lol. Let the oil in an engine run dry in a 1.3 Escort.

Most failures I read about are from broken parts or terrible maintenance. Rare I see pure power or unmapped mods killing engines.

That said I've always wanted my afr's right and efficiency being tip top.

I've broken pistons through det I'm afraid to say. But it was extremely obvious, I kept my foot in it because was racing (beating) my mate.
Took him a while to get all the oil off of his windscreen

PMSL @ the oil on the windscreen.

I've always had the most fun racing my mates, win or lose it's always been a laugh.

At SSO one year, it was absolutely pissing down, racing my mate. We both went for it on launch and sat side by side spinning the wheels for a second or so before our cars took off. Great fun.

9:1 compression ratio and too much timing on the base map, thing was pinking it's head in on boost, very audible, very obvious. Also very fast, didn't want to loose now did I?

If you don't break anything you've never done anything!
I bet if you ask any of the professional tuners on here if they have broken engines through mistakes or pushing too hard then they will say yes.
I started off like most decent folk, tuning 2 stroke motorbikes at 16. A hole in a piston back then wasn't a major problem!

To be fair I was running 17s with this method until I changed the arb and crank pulley.
Now I do 12.8s and have had the same tank of fuel for 6 months and do 200 miles a week.

Funny on another thread you are saying you ran 12.8 with 265bhp!!! ...and on another you say 12's can't be had with under 400bhp!!!

LMFAO at the world's worst forum troll.

I suppose oil thinning due to heat as killed a few engines.

I hear a lot about engines may blow if you run a full decat unmapped, especially on a 2.5 but of all the failures I read about non seemed to have been caused by it. It's usually a faulty fuel pump, missed gear or split hose etc.

It'd be nice (but morbid) to see an Impreza engine failure league table.

Yes! Do it! I'll have my middle end failure on there, 97k miles, PPP 2003 wrx.

Hi Matt

You shouldn't judge on power what car is running and what times they're doing,you need to take to account at least tyres what he using and if he at least experienced,our best time on first attempt has been around 13.5

Have look,we are run non meth map(452bhp) on our wagon and we are been unable get car under 12.5,on next run we are switched to R888 and our best time has improved to 12.1 but still we are been unable to do better time

Best time what we are done on the wagon has been 11.8 on R888 and meth map(490bhp) at very hot weather and ACT temps has been quite high...

Hope this help

Thanks,Jura

A lot depends on the day and the conditions too, yes the driver is a big influence. However with the best tyres and driver in the world an impreza with 200hp will never do a 10....
Power makes a fast car, along with having the hardware and experience to use it

Come on then guys, how much grunt would be required to get 9.99?

In a stripped out classic on slicks.

My guess around 700bhp.

I don't judge individual cases as such but rather consider many cases of cars running similar times at similar powers. There's definitely a pattern and exceptions are few and far between.

I know all about traction, I ran my best 1/4 on budget tyres full of wet mud! I should have beaten Mickey's 12.4 but I stupidly parked in a muddy field before my last run and got some horrible wheel spin and the back end was very twitchy for 50 yards.
This is interesting piece about tyres from a World Record holding Scoob driver:

INNOVATIVE TUNING: This car was half a second slower on 275 wide super soft road course slicks and would be even slower on street tires, probably high tens. I was spinning through 4 gears on the 275s. On 245-255 street tires it would spin straight into the limiter in 4th gear.
Adding weight would help traction a ton so it's hard to say what this would involve. I'm confident I could do a 10 with the power I have now in your car on good street tires, but I'm not sure where it would fall in the tens.
I think at the powers levels I mainly compare WRX/STI's at (225-450bhp) wheel spin is only worth 0.1-0.3secs perhaps.

This is interesting too:

INNOVATIVE TUNING: You also can't compare power to trap speed as gearing varies. For example, my 1/8 mile trap would be much better if I could use 3 gears instead of 5 to get there (07 gearing vs. 06 gearing I have). Peak power vs. power under the curve totally throws off any guess at power to weight. It's fun to guess though.
