Agree on that,off course conditions will make or break the times,but as you are said,when there is no power then,you shouldn't expect from 200hp car to make 10 sec pass

Thanks,Jura

Not sure how much,but I would suspect high 600bhp and possibly early 700bhp,but as above gearing will be important

I prefer long ratios on drag strip and my brother too prefer this too,as many will say 06 DCCD STI box is best for drag strip,just due longer ratios

Hope this help

Thanks,Jura

I'd love to know the lowest power Subaru to hit 10's.

Mikee Singh's SCR classic weighs 750kg, a 1/4 calculator states 288bhp will see a 10.99 pass.

That'd be a fun car to own! Don't even have to worry about emissions come MOT time!

RS_Matt

Why did I just read this!!

I'll have to concede the Newage STI is the better car now.

Do you know what the ratios of the 06 STI box are Jura?

2003 WRX box is:

3.166 2nd 1.882 3rd 1.296 4th 0.972 5th 0.738

All classics?

1st 3.785 2nd 1.945 3rd 1.500 4th 0.994 5th 0.780/(0.735 WRX) - Final 4.11 (3.90 WRX)

04-05 STI

1st 3.636 2nd 2.375 3rd 1.761 4th 1.346 5th 0.971 6th 0.756

Does the Hawkeye box just have a shorter final drive that's the same as the WRX?

I can't find any info about the Bugeye ratios.

Hi Matt

How to say,6 speed is better choice because is lot stronger than 5speed,you can run late STI gearbox without the issue at low 700bhp and I think few guys run them at low 800bhp without the issue

Gear ratios of the 06 STI

(1st) 3.636, (2nd) 2.235, (3rd) 1.521, (4th) 1.137, (5th) 0.891, (6th) 0.707

Bugeye ratios I've somewhere and too PPG ratios which we are run,I would say PPG is best gearbox if you are thinking about the drag strip more and you are not running high 500bhp,beyond 600bhp I would go with probably dog box or Albin Kit which have similar ratios as PPG

I know only speed per gears,but in 3rd at 7800RPM we can do 112mph and in 4th at 7800rpm we can do around 144mph and 5th this depends on the final gear and diff,gearing is very similar to the 4EAT(Autobox) what we are run

And probably best drag strip box,then I would speak with Toni Rigoli about his box or you can go with Sequential box,depends on your budget,both choices are expensive

WRX is not bad car,but if I would go again with Subaru,I would go with STI,its better car in standard form,WRX is nice car as daily car

And if you want to build track car,get classic,its better from only one point and this point is is not so heavy like New age,



Hope this help

Thanks,Jura

Cheers that man!

From what I've read tonight about handling 750bhp stock and having shorter ratios/final drive the Hawkeye STI is one seriously bad *** car.

Best Scoob ever made?

looking on that page Classics run all manner of ratios and the BUG looks like it has the same ratios as the blobs.

TBH this above site looks to contradict this one

http://en.wikipedia.org/wiki/List_of_Subaru_transmissions
wiki: MY03 WRX: 1st 3.166 2nd 1.882 3rd 1.296 4th 0.972 5th 0.738

Gearhack: US MY03 WRX: 3.454 1.947 1.366 0.972 0.738

I'm not so sure what's what now. The JDM Newage STI's seem to have impossibly short 6th gears, they must be disastrous on fuel compared to the UK STI.

RS_Matt

So basically Newage boxes

3.454 1.947 1.366 0.972 0.738 - my blob WRX
3.636 2.375 1.761 1.346 0.971 0.756 - fat thomas UK STI
3.636 2.235 1.521 1.137 0.891 0.707 - Hawk box UK STI
3.636 2.375 1.761 1.346 1.062 0.842 - JDM STI

3.166 1.882 1.296 0.972 0.738 - JDM WRX box, but different final drive and I'm not clued up enough to be able to compare.

RS_Matt

US Legacy L & Brighton MY01-02 has these ratios with the same final drive, straight fit? Are the non WRX boxes ok for 350lbft?

3.454 2.062 1.448 1.088 0.780 - TY754VCBAA

That'd probably improve my times and make general driving more fun.

I guess I won't be seeing the 9s this year coming then, maybe 2016 then.

Drag racing - Don't forget the auto's

4 speed auto: 1st - 2.785 2nd - 1.545 3rd - 1.000 4th - 0.694 Final drive ratio - 4.11

RS_Matt

I'm really out of my depth here but what kind of money would it be to install something like a 4EAT and would the transmission losses make it only suitable for 500bhp+ Imprezas?

Quick read on NASIOC states in standard form the stock 4EAT is only good for 300lbft, so I guess the big power builders have uprated or race spec built 4 speeds.

Hi there

You will see,what power are you want to be running ? And what weight yours car should have ?

Thanks,Jura

Agree about the 4EAT,they're great for drag racing,but in standard form they don't last

Thanks,Jura

You really are obsessed with beating my time that I set in 2008, aren't you?

If that makes you happy Matt, then so be it, I couldn't care less.

boosted

Are they? What about the stall speed on the torque converter? Is it not a bit low?

Maz

iTrader: (34)

Only a fool would use the 4EAT transmission in standard form for dragging. Torque converter upgrade would be a prerequisite I would have thought.

RS_Matt

You haven't modded yours going on 7 years?

he has 430 bhp, made up to fit in with a drag racing thread

Why should I? It's a daily driver.

Well I have changed bits and pieces, but, not looking for more power.

ive taken all the badges and stickers off my car so i must hold the record as ive gone from 260 ish bhp standard to around 160 then and still ran the 12.8 with passenger

Sounds expensive! Also would destroy the cars drivability

3000rpm - 3200rpm is the right stall speed for a daily driver. That's the standard stall speed for a turbo convertor. However, after this length of time the lock-up material in the convertor is probably disintegrating, and blocking channels in the valve body.

On stock convertors:
Non-turbo stall is 2350 - 2750
Turbo stall speed can range 2650 - 3300
A torque convertor is like a clutch. Fully off the clutch pedal, is equivalent to the stall speed on a torque convertor. But like a clutch, that's still partly depressed, a torque convertor will still give forward movement, before the stall speed is reached.

For max acceleration the stall speed should match the rpm at max torque, of your particular set up.
For a turbo daily driver, the stall speed should be the point a which the turbo begins to make boost. As the turbo increases boost, the the stall speed increases, may be by 400-600rpm. So, on a turbo, it depends if your considering stall speed on or off boost.
Between those two points is a daily driver or drag car - you choose the principle focus of your car.

its all quite interesting the auto box etc.
but matts not got a dedicated drag car all he has is a £2000 quid old wrx with an sti turbo and spoiler plonked on the back.

boosted

I don't rev my car much past 2000-2500 when driving off boost

RS_Matt

I have a £75 WRX turbo.

...over 20 years old too, and it still helps me beat higher powered, less laggier 2004 STI's.

RS_Matt

160hp at the wheels is roughly right for a 430bhp STI.

fat-thomas

12.8 with a passenger..................nuff said at standard unmapped un ppp sti power which is around 260bhp 70 bhp less than you

RS_Matt

I wouldn't call a jet engine a passenger.
