Marty, you have got a long way to go then if you want to make a 10 second run.

 

.

I will be in the 10's next year .already removed 40kg from car since 11.7 run.Also going on race fuel and mickey t's next year

Hi Triple. Yes, RCM's quality is excellent. What are you running at the moment mate (bhp).
They have a brand new Twisted Turbo kit coming out end of Jan / early Feb.

Good luck with yours Triple

 

I think daz is currently running a 1ltr polo

 

Top thread Skullfudge, good luck with it all!


P1MARTY, your car was also awesome, there's alot of room for improvement on those drag strip times though, get down the strip and start practising!

A classic with 500ish should see the 10's fairly easily with a good launch/driver.

 

That's my best time too, but haven't taken the car onto the drag strip since SSO 2007. I'm kind of scared of breaking something in the drivetrain if I try to launch it properly - which I never need to do in the Time Attack.

I would think mine would be well into the 10's with Steve Darley or someone else like that driving it - but then I'd no doubt have a broken gearbox too

So only track stuff for me now -

 

What would you class as the weakest link in your transmission Terry ??

 

if i was driving it? 2nd gear

Seriously, the power Marty is running should see a 10 already in the P1, its just sometimes the driver that makes a difference.

I remember way back when Trout/Rannoch owned the grey Lateral car and that produced 555bhp, and he couldnt go any quicker than 11.7, despite months of trying. I eventually got a go when Mark bought it, and on my very first run i did a 10.92 on Bridgestone S02 tyres!

So, in short, you can have all the power in the world, however it counts for nothing if you cant launch it or change gear!

Spending money on race fuel and drag radials is pointless IMO, untill you have improved your technique.

 

Standard driveshafts, although all 4 have recently been replaced for a newer set. I have a carbon prop (to fit) and the gearbox is straight cut PPG dog 1-5 and I have straight cut drop gears too. So the gearbox is pretty robust and the clutch is an exedy triple plate carbon jobby.

So the driveshafts are the weak link and I'm not overly interested in buying an uprated set as I have spent enough on it already

However next plans are to remove weight from the car - using GRP panels, plexiglass and cutting out any unwanted bits of metal and generally finishing the car - so that next year it is very nicely presented

 

Never broken a drive shaft yet Terry, always been the box.

 

I know what your mean about technique ,last time i went i manged to get a 60ft time of 1.72 on 18" T1R's .
Still having trouble changing gear quick ,i know i am losing a bit with a uk 6 speed box ,only good thing i suppose is every time i go i get slightly quicker.
Problem is at the back of my mind i'm concerned about getting the wrong gear and over reving the engine.

 

Hi Marti.
I have not put mine down the strip yet but I know exactly what you mean.
When I am shifting through the box quickly, on three occasions now I have gone from 4th to 3rd instead of 4th to 5th. It's tooooo easy to do. Luckily I realised before I released the clutch.
I was telling Matt about it and asked about the possibilities of going to a sequential box setup. He said it was possible but would be a fair amount of work, then I would also have that constant wining noise.

 

I think if you want to get a 10 Marty your going to have to stop worrying about the box and just go for it.

Im running less power than you with about the same 60fts...

By the way when are you changing into 2nd gear?

 

I have got my newage spec-c down to 11.7@120mph at pod with 420bhp + 50 shot of nos so you should be walking a 10sec run really with that type of power, think it must be down to gear changing

 

I know its my gear changes ,probably does not help the gearbox crunches going into 5th which slows me down
my 1/8 is 97mph at 7.6 sec.

 

My 1/8th was 7.56 @ 96mph so not alot in them, am sure u will get your times down before me

 

Marty - what diff ratios are you running? 4.44s or 3.9s. I would have thought if 3.9's then you shouldn't need 5th on the strip.

 

LOL, me neither, but know a good few others that have - Bob Rawle and Mike L both spring to mind.

 

You will on a 6 speed

 

Don't the latest six speeds allow you to just use 4th on the quarter?

 

Surely if the can had the power then 4th would be too short?

 

4th in the later 6 speeds is longer as it was mated to the larger 2.5 engine, nice to see you back Daz

Banny

 

hats off to you fella

 

Im on the limiter in 5th on a uk ratio 6speed.

A few mph faster and ill have to go into 6th.

 

What year 6 speed though?

 

2004 iirc or maybe newer. Its got the later style front shafts

 

4th gear on mine will do 110mph,

 

My 6 speed is 2004 non dccd,i get 110mph in 4th .When i go over the line my speedo is reading around 135 mph and yet real speed is 124mph.

 

Hi Guys

IIRC the later 6 speeds are higher geared to the following.

I think the later 2006 hawkeye UK STIs2.5 have the following ratios, as does the Forester STI (The Forester does not have DCCD thou)

Ratios 3.636, 2.235, 1.521, 1.137, 0.891, 0.707

This is the same box I use and the speeds I get in each gear.

Theoretical Speeds at 8000 rpm
Tyre set 1 43-70-103-137-175-221
Tyre Set 2 42-68-100-134-171-215
Tyre Set 3 40-65-97-129 -165-208

Set 1. 20/65-17 Michelin T04 Pattern Moulded Intermediate TA00 Soft compound 200mm wide 650mm Diameter
Set 2. BFG Drag Radials225/45-17.
Set 3. Toyo R888 225/40-17

On the strip, I have to raise the rev limit in 4th, to 8250-500 as I cant go any larger on tyres, (even with rolled arches and coilovers) and changing to 5th loses too much time.

The later 6sps are in demand and command high prices. I believe Rallispec in the US will sell you a wide ratio gear set to the above ratios for you existing 6sp for $1000ish.

With hindsight I realised a 5 sp with the correct ratios and 3.9 cwp's would give higer gearing in 4th, but brings its own issues.


Hope this is of use.

Sleeper

 

wow stunning spec and a stunning tuner to use no doubt....RCM really do look after your cars and i hope you can use the power on track and strip..

I currently ran a 11.08 sec 132mph with my set up and i don't think its quite 600bhp yet as i'm only using a GT3040...


Good luck Fudge
