For replacement discs, Alyn at ASPerformance is usually quite good.

Or I'm sure Martin offers plenty of brake bits, and possibly some cheaper disc alternatives to the full on race versions as well.

Christ that looks like it pulls soooo strong! Nice to see it gets driven properly too. Bet its an awesome bit of kit to drive. Shame about the issues youv'e had with it but spose you have to expect some bits to go wrong when running such a lot of power from a tuned engine

cheers mate il have to look into that, I don't fancy paying Ł1000 for a pair of discs, the pads look nearly new.

it is relentless mate once on song, glad you like it heres a drive by on my private 1/4 mile tarmac

I got 90mph up my road earlier which is the limiter in 2nd gear ! lol

Thanks for the info your learn something new everyday. I know a fair bit about fords but when it comes to any other car im fooked lol.

Dont half sound nice too! Makes me want one lol

I never stop learning mate

gotta love a screamer pipe



I got a plot today in din correction so its exactly comparable to the old housing dyno plot

old plot on 0.84ar housing




new plot on 1.06ar housing, dyno boost monitoring shows both plots running about the same boost

scoooby slayer

iTrader: (4)

its very difficult to gauge the gains/losses without being on the same plot so I went in art and marked off the old small housing power/torque for an overlay





I cant help but wonder what she might of made if id of put the 1.19 ar housing on ?
if the gains remained the same at din correction in theory it would of been nigh on 700 hub power

scoooby slayer

iTrader: (4)

well the extra power is definitely real

30 to 130 mph is now down from 10.89 to 9.76 seconds !





and managed 0 - 100 mph in 7.2 seconds with plenty of wheelspin there is definitely a 6 second in it im sure, it may need a full set of r888s on it for pod




also smashed my terminal speed record with this car, it was 123 mph, now 129 mph in the 1/4 mile and 11.7 with another shit start


the torque steer in first gear now is getting quite bad lol
very happy though it pulls like a train

Very cool matey. When are you going to santa pod.

bluntys1rsturbo

brilliant results fella glad you stuck at it and finally got there in the end, anything that does 30-130 in 10 or under is a seriously quick car.

888s will defo help your 1/4 times at pod but have you considered getting a set of drag slicks on there or do you prefer to keep it strictly road legal for time comparisons?

scoooby slayer

iTrader: (4)

im not sure mate we are flat out at work on machine repairs at the moment, il put a thread up though when im going incase anyone is wanting to go aswell, I hope someone comes I may need a push if I break it lol





cheers mate, and that is with 3 h pattern shifts aswell, I think if I had an r35 gearbox with instant shifts it would be in the 8s, the supra did it in 8.8 seconds so im getting close to it.

its strictly road legal tyres for me only, I may even just try the vredesteins its just getting to the point where its struggling for traction and spinning all 4 wheels now lol, once the tarmac is warm it will help aswell still abit cold and damp at the moment.

Give us a ride and I will push if it breaks

salsheikh

glad its all working again and boy is it pushing out some power. some slicks for santa pod might be a good idea!

wide ka

top work!

what do you use to time it?

scoooby slayer

iTrader: (4)

better still meet me there mate in your twin turbo beast and have a go

we can push each other then lol

I am pondering on tyre change, il see how she grips when its dry on road tarmac first, she would beast launch with r888s that's for sure

I have a racelogic performance box accuracy is within 0.05% 50cm in 1 kilometre

not cheap though with all the extras its Ł540 !

Caddyshack

Wow 7 to the ton is very, very quick. Anything under 10 in my book is a properly fast car. Not many supercars / hypercars would keep with that thing!....Zonda.

scoooby slayer

iTrader: (4)

thanks, it certainly is starting to tank along now, imagine if it hit and held 2 bar of boost, I would be deep in the 6s then for sure
I need to try and just leave it be now though so it doesn't have the same demise as the supra did lol


I just went back through the thread and got the last in gear pull times I did for robw last year.
il overlay what shes done now from the new plots I have


.......... old times ............... new times

30 - 50 mph 0.94 seconds ....... 0.91 seconds
60 - 80 mph 1.49 seconds ...... 1.29 seconds
70 - 80 mph 0.77 seconds ...... 0.65 seconds
90 - 110 mph 2.21 seconds ..... 1.91 seconds
115 - 130 mph 2.5 seconds ..... 2.15 seconds


it makes all the hard work feel worth it with gains like that from nothing extra except a bit larger turbine housing and optimised setup.

Very impressive.

Rod-Tarry

Heres something to ponder

11.8 @127 with 500bhp PF Daddy Thrash 2002
11.5 @138 with 700bhp PF Topspeed run 2004

Your terminal sugests Power in the low/mid 500's.
We are expecting 150+ with present Spec.
These are facts & not meant to diss your figures.

scoooby slayer

iTrader: (4)

how much did you weigh rod ?

my gross weight is about 1700kgs, you must of been a good bit below that in a saph around 1400 - 1500 kg id assume ?

heres is a good indicator plot I have that correlated well with my r32 gtr terminal and the supra terminal for weight and 700 whp





1700 kg 129 mph is about 617 whp

it would take over 800 crank hp to terminal 138 mph at 1700kg rod


I think ive done well at 710 hp 129.7 mph if you trapped 138 mph at 700hp being lighter.


150 mph terminals in a full weight road gtr with h pattern box would take about 1000 crank hp imo.


ive just checked on your site your 60 - 130 mph time on there is 6.25 seconds at what power was that 750 hp ?

ive recorded 60 - 130 mph in 7.8 seconds so far which is about right imo considering the weight difference.

if you only trapped 138 mph with 700hp I don't understand why you think my car should do 150 with the same power and a lot more weight ?

scoooby slayer

iTrader: (4)

cheers mate I think so to considering how heavy they are and 4wd aswell which aides grip but cost power in drag and the extra weight.

stevieturbo

I dont think your speeds are too far off, and it's also harder to compare 2wd against 4wd. Plus the weight factor too, A Sierra will be a good bit lighter than a R33

Typically a 2wd will trap higher more easily than it's 4wd counterpart. The 4wd will have much lower ET's though, which is all down to grip.

Less time on the track = less time to achieve said speed.

scoooby slayer

iTrader: (4)

that's what I thought my view is the times prove it is 700+ crank hp, given its h pattern shift full weight road car.
ignoring the launch 30 - 130 in 9.76 seconds imo proves the power for a h pattern 1700kg road car, im not really sure what rods talking about tbh.
id understand if id put a dyno plot up showing 850 hub hp or something silly like that.

maybe rod got confused and thought its a saph maybe ? but even then he expects me to terminal 12 mph more than he did with a saph ffs lol

according to Wikipedia dry curb weight 2wd sapphire 1206kg, r33 gtr 1530kg, 320kg is a lot of extra weight like carrying 3 fat men in the back lol

scoooby slayer

iTrader: (4)

ive just been thinking about my supra 0 - 100 mph time and it being comparable to the r33, and theres something I forgot.

the supra was run with a 12" rollout in 1/4 mile mode on the GTECH, which means the clock doesn't start till 5 mph and I recorded 0 - 100 mph in 7.3 seconds





so with that in mind although its not accurately timed to be comparable I need to time the r33 in the same way, so starting from 4mph allowing a 12" rollout I come out with this so far





starting at 4mph ive 0 - 100mph in 6.9 seconds, so in comparison terms 0.4 seconds faster to 100 than the supra

and 5 mph - 130 mph in the supra was 10.6 seconds, the r33 is doing it in 11.1 seconds and with a lot less boost, I think if it held 2.2 bar of boost like the supra did it would be almost identical.

turnover

You can't drive Rod lol
My pal has a 2wd saff t34 on greys with chip and runs 12.1 all the time on his everyday tyres
You work the power out,can't be no more than 390 400hp with the boost wound up

stevieturbo

Give it another few hundred HP though and it wont ET much faster though.

The 400hp car is probably only trapping 110-115mph

scoooby slayer

iTrader: (4)

I had the same troubles with the supra I only managed 11.9 but I hit 134 mph lol


I can honestly say though everytime ive been, and I mean every single time when I launch I have had bad wheel hop to the point I always let of, im a mechanic and my brain physically wont let me keep my foot in lol

and that has been on a gtr and a supra.

I would always have the shocks softened out abit to try and help squat, so for my next run I am going to have the shocks on full hard, in the hope with it being stiffer it will help stop the bounce enough so I can keep my foot in.

I have never had trouble on the road as its not as grippy, im also gonna go with normal road tyres to start with and see how it goes before I fit a full set of r888s.

turnover

Agree Steve but I was on about the time not terminal

scoooby slayer

iTrader: (4)

I think rod was only really using the terminal to calculate power, but im yet to be told why he thinks I should terminal 150+ mph with only 710 hp lol

SiZT

I think he meant he'd expect to see 150mph on his new engine

scoooby slayer

iTrader: (4)

ah I see that explains the 150 mph part.

still doesn't explain why he assumes ive only got 550 hp with a 129.7 mph terminal at 1700+ kg ?


ive got a 0 - 140 mph log now aswell it took 12.9 seconds.

turnover

If your good with calculations work my old time out and you might be able to calculate yours
0-145 mph was 9.7 secs and car weight was 980kgs but 1085kg with me in it power was 630 hp
Oh and obviously the mph is determined by the 60ft so on vid link it's 143mph but I had same time at 145mph

xr2wishy

iTrader: (2)

sometimes rods age doesn't allow him to think outside of his saff......
extra weight really damages acceleration, also "turnover", i bet the 400bhp cos you're on about won't make it to 200mph which is why rods 1/4 isn't mega fast as the power needs to be spread over more revs.

good numbers being thrown about, i love a bit of math to back up feel in the pants claims.
power to weight figures are very useful to have

scoooby slayer

iTrader: (4)

my plot above mate shows it all.

if we work on your weight being 1100kg

at 143 mph for 1100 kg is 550 whp, + 15% for rwd is 632 crank hp so about right, also my supra and r32 made the correct terminals for the wheel power.


now looking at my r33

1700 kg

for 129.7 mph at 1700kg is 628 whp, + 20% for 4wd is 753 crank hp


now looking at a saph

1400 kg

for 138 mph at 1400 kg is 625 whp, + 15% for rwd is 718 crank hp


all of them are about right for there weight/ power for the terminals.

maybe rod forgot that more weight needs more power in the 1/4 mile, where its not as relevant at brunters.

heres the chart again I got on very good authority and its correlated well for me so far for terminal speed and hp.

scoooby slayer

iTrader: (4)

I love it mate tbf

I like to back up my power with real world performance, after all we cant race a dyno plot

turnover

Mine was actually around 500 atw as the wheel figure can't lie ,anyway you graph suggests 9.7 so it seems a good guide

Sonic Boom

iTrader: (11)

Me amd the 3 Door probably weigh near the 1400kg mark and with 590bhp at the fly so around 500 at the wheels I've done a 11.9 @ 128mph.
So the table seems to add up terminal wise, although i'm a fair way off a 10.4 quarter lol.
