How fast can a Newage accelerate with the stock internals and 5 speed???

State of tune so far →

3 of my 4 quickest runs:

KG-T WRX 333bhp 12.45 secs @108.96mph - YouTube

333bhp 2003 WRX 12.44 secs 0-60mph in 3.8secs!!! - YouTube

Big thanks to KG Tuning (The Wife ) for fixing/modding the car regardless of the time or weather!





Ultimate goal is to get into the 11's or hit 0-60mph in 3.5 secs with less than 335bhp/310lbft.

You haven't said what chassis will bear the brunt of this epic endeavour, but I can't wait to see it done in a newage shell though.

Sub 12's at 350 won't be easy. Not impossible mind, my Sti Ra ran a 12.4 at only 300bhp.
If you don't mind me asking, how come you've used so many different mappers?

Good project by the way

bob from aztec has done 11.7 with 340bhp but his gearchanges were absolutely brutal on a ppg 5 speed

slower run from bob

Anyone under 11, with 400?

I used AET because they are just down the road, I didn't realise they bring/brought in Matt to remap their cars. When my car was diagnosed with ringland failure one of the causes guessed at was the map so I used Tweaks for the next one after PVD Power had had a spell at mapping but I still didn't get anywhere near the 1.5 BAR I was looking for, even though they told me they had. The next mapper and one of the most reputable in the UK forgot I'd agreed to the date he suggested. The week after I wasn't actually going to get the car mapped at Scoobyclinic but they said they were free to do it whilst I was there and Pat has a good rep - so why not? They were dead against running 1.5 BAR though, no matter how I phrased my reasons for wanting it/getting away with it Anyway Pat Herborn managed to get me the kinda rise in boost 4 previous mappers had failed to do.

Before the last map the car got timed at York raceway into a strong head wind at 13.3 with a timed 0-60 of 4.5 secs.

I'd think with 333bhp and a massive step up in torque I should be circa 12.8 and 0-60 in 4.1 secs.

As I'm planning zero engine mods from now on there will be some significant weight saving plans for the car coming up. I'm going to push for 1000kg but over many years.

Polycarbonate
Parasitic improvements
Further rotational mass tweaks.

You mean running in the 10's?

RS_Matt

Thanks for post, things like that give me hope and push me on.

I wonder if Bob holds the record for a sub 350bhp "real-world" Subaru

In a classic though Banny.

Yes. If 11.7 has been done with 340, then, in the slower brackets, allowing 0.1 reduction for 10bhp - I wonder if, as you say, 10's are possible at 400 ish.

banny sti

iTrader: (68)

Yep, in a newage you would really need to strip it out and get the weight down to classic levels to even get close to the 11s.

A rule of thumb I always went by in drag racing, if you want to go twice as quick you need eight times the power. I know that's way beyond what you are suggesting, but we're all travelling along that road when we try to go faster.
You can't apply simple proportioning such as 10bhp=0.1sec to speed, for one thing doesn't drag (impedance not the sport) square with speed?

fat-thomas

iTrader: (4)

a new age car running in the ten seconds bracket is going to take far far farmore than a wrx with the seats removed and 340 bhp

2pot

iTrader: (3)

As a rule of thumb it works well. As does 7.5bhp = 0.1 sec in the faster brackets. Obviously there are many variables - weight, power etc - and faster still, aerodynamics.

fat-thomas

iTrader: (4)

another factor is with the extra power needed and the extreme launch that will be required the 5 speed box won't cope.
also you have gone through some extreme weight loss on the car then plonked a heavy sti spoiler, skirts and bonnet scoop on a wrx, id say the spoiler weighs the samne if not more than the parts you have removed.
trying to make it look like an sti won't make it go like one

ditchmyster

iTrader: (7)

This is going to sound a bit RS Matt, but I removed my spoiler off my Type R and it was noticeably faster, all the big spoiler does is create drag up to 120mph where it begins to help with down force when high speed cornering.

And it weighs a fookin ton.

fat-thomas

iTrader: (4)

this is 100% the point why reduce all that weight then add even more by fitting a big spoiler from an sti.


surely you are now back at square one and what you have is a mildly tuned wrx that wont have a hope in hell of getting anywhere near 11 seconds nevermind 10

2pot

iTrader: (3)

There's another rule of thumb:
75/100lbs reduction = 0.1 sec

RS_Matt

Beauty of my car being a WRX means only 4 very accessible nuts holding the boot spoiler on! It is fooking heavy though and on the car when I bought it . Maybe a painted Carbon Fibre replacement will be thrown into the mix one day.

Even the STI skirts were lighter than the OE WRX items. TBH though I don't want to cross the line looking like a Vectra.

fat-thomas

iTrader: (4)

most of your threads are utter crap but I think this one is sort of serious.
to get anywhere near your target time of ten seconds requires far more bhp and far less weight.
also a much stronger drive train so all in all a lot of money.
there are hundreds if not thousands of lightly tuned imprezas like yours around and none would get near an 11 second run never mind 10.

RS_Matt

I think when I said "get into the 12's then ultimately 11's" I meant scraping 11.9

But hey, if you're offering sponsorship!

NOTE TO THREAD READERS - drag race hating fat thomas IS A PREVIOUSLY BANNED TROLL WHO LIES THROUGH HIS TEETH

tom likes to troll people with stickers or parts off a different model but...

fat-thomas

come matt a serious thread for a change...
its about power to weight ratio mostly

you have a relatively low powered car and in the grand scheme of things the car hasn't had any significant weight reduction.
how on earth do you propose to get into the 11 second time bracket without adding significantly more power which as you are technically around the limit of wrx internals and gearbox is going to cost several thousands or drastically reduce weight which is going to render the car useless as an everyday car as its along the lines of perspex windows etc.

You're going to need more power, and a more practice Matt, to even get to low 12's. You'll need a hell of a lot more power to get into the sub 11s bracket. SteveBT's is over 600 and his runs high 10s quarters. His is full weight though.

Yours is heavier than mine, and similar power. I'd assume more lb/ft than mine. If you aren't in the 12's now then you'll have to try a different approach

Holding the revs at 4K and slipping the clutch whilst releasing the handbrake isn't going to make you quick, I'm afraid. You need to drive it harder.

6k rpm, blipping the throttle on the startline, so the turbo is actually doing something, and dump the clutch. Both Andy Forrest and Steven Darley advised me to blip the throttle, and they know a thing or two about drag racing.

Go hard or go home!

5K launch


6K launch

RS_Matt

I'll probably get braver when 11 seconds gets nearer! As I keep saying your time is my current target muhahaha.

My starts are ok (very happy with 0-60 in 4.5 secs with 299bhp and very low torque at the time) it was the last 1/8 that was holding me back, one of the slips told me I was 79mph at 1/8 and 88mph at 1/4!

Hopefully now I have a restrictor pill fitted and more power/boost that very long 3rd can start propelling me.

The car feels so much quicker now after Scoobyclinic cured a few issues and mapped it. The next run should be very interesting.

Not sure what the car weighs at the moment, I really need to visit a weighbridge. I'd guess around 1280-1300kg. Car undertook a professional weight saving session at a specialist years ago, the pile of removed parts was substantial, I recorded as many parts as possible, not sure what to list a lot of them as though.

They were going to remove all the aircon ancillaries from behind the dash but we ran out of time, I will rebook though at some stage.

Weight wise I'm probably just under 1300kg but still got a long way to go. I won't be using perspex for anything that's for sure.

Good luck with that... The quality of the strip makes a big difference you stand your best channce at shakey or pod. Anywhere else is virtually impossible.

Mine does a 1/4 in low 11s and I will be looking for a 10 on saturday if the weather holds up on a sub standard strip. But that is a FULLY stripped classic with 500+hp. It has no door cards interior, sound deadening, spoilers etc!

So you are very keen to get something into the 11s....

RS_Matt

Hope you do it, 10's is the ultimate but way beyond my funds or driver skill.

My car is getting a bit skittish in the wet in a straight line, 500+ must be nigh on unusable on a greasy road? Would it snake when boost comes in?

JGlanzaV

iTrader: (3)

Yep pretty much, even part throttle and you can feel the back end moving around! Last time it was mapped it pulled 535hp on the meth map and in slightly damp conditions it would spin all 4 wheels up in 4th gear....

Bollocks!

People think drag racing is a piece of ****, in essence it is or should be, it's a lot harder than they think.

I did my first ever drag race at the Pod on 8th Oct 2006, I did a 14.something. I'd only had it a year, and it's a hell of a long way to drive to potentially kill your car.

2 years later, possibly one of the runs in the videos above, I did my 12.4 Only things that had been changed in that time was the Nur Spec and FMIC fitted. I just got harder on the launches and gear changes.

Gearbox, fresh recon from Alyn @ AS Performance, and clutch had only been in the car 2 days in those videos.

RS_Matt

What's bollocks?

I'm not totally confident 12.9 isn't beyond my ability.
