djtimo

What wing is that mate. Supports look nice.

you wanna see the creation Tim (djtimo) was running on his twin turbo car this year was interesting to the least Gets few mad looks!

Will be doing a trackday soon as i can so will feedback info as always.

New fan and Rad pack fitted yesterday! Custom welded AN fitting on lower tanks. Fully built up ready for install. Fitted! Loads more room for rad to exhaust now infant of the block. Car has been re-filled with 10% glycol 90% deionised water plus water wetter. All bled and running OK. Not been able to test it as it has no MOT ATM.

More weight loss today. Ditched the brake and battery covers... Looks crap goes faster. Weight of the cover and battery tray with some unused ground wire. Total weight loss for the covers and misc bit was 1.85KG Also fitted my short aux belt after the pulley delete but ended up removing the belt tensioner as it was seized solid and needed cleaning and oiling Weight loss for this = 1.85KG TOTAL WEIGHT LOSS SO FAR = 73.53KG DRY CAR WEIGHT = 1406.34KG

Mishimoto fans IIRC don't have 3 speeds like OEM. They also run both fans at the same time rather than one for AC and one for cooling rad.

Hey man, I know you build is mega too so thanks! I have been reading about your over heat issues but I'm hoping this helps me.. If not ill have to buy an OEM rad to test with! For brakes your main gain from 2 piece disc's are unsprung weight reduction IMHO.. Feel is the same an daily comes from pad choice. Im running traded line, good fluid, stop tech aero rotors and carbon lorain RC5+ pads.. the only thing that really made a big deference to feel and bit was pads, Ive tried OEM brembo, DS2500, Performance Friction, and CL Rc5+. cold bit OEM pads are best as soon as you have heat in them CL pads are miles better than the rest..

I have also removed the full AC system but didn't take any pics of the weights!! Doh... IIRC the total weight was 11.5KG... This was 9kg for the compressor 2kg for condenser and the rest was on bolts and mounts/lines. New passenger seat should get me under the 1400kg barrier soon! (Carbon boot/doors would see me around 1350kg!) Weight loss for this = 11.5KG TOTAL WEIGHT LOSS SO FAR = 71.68KG DRY CAR WEIGHT = 1408.19KG

More progress on the car today. I finally had time to pull the Rad and remove the old pulley etc. Few pics of the job Pulley that was about to be removed... Removed... Braket and pulley off.. Corner of brakes cut off and made into a spacer for the power steering pump. Weight removed.. 1.2KG (scale is off due to no bowl ontop soil reading a 130g low. As the rad was out and OEM fans were out I weighed these too! 3.9KG Minshmoto fans 3.4KG Inner Boot seal 0.9KG Weight loss for this = 2.8KG TOTAL WEIGHT LOSS SO FAR = 60.18KG DRY CAR WEIGHT = 1419.69KG

Sorry i don't agree at all.. Motorsport is just as much about the noise and feel as it is the performance for me.. I love doing unsilnced days as the car "feels" better from the driver seat to me. I also really enjoy hearing the car (my car is loud at 107/108db static and louder on driver by) so you can hear it well through the helmut. days where I have to run extra silencers aren't as fun imho..

I run stop tech's on mine.. been great !

Basically I have worked out surface area for 3 different rad set ups.. The current 36mm 13-14FPI I have vs. 36mm Hyper core 17FPI vs. 53mm 13-14FPI. The thinner 36mm hyper V core is mid way between the 36mm normal core and the 53mm normal core. I can't be bothered showing all the working out but its not far off. Im fitting the bigger 53mm rad which has a surface area around 180m2 vs the 121m2 in my current system. The other benefit of the 53mm rd is high coolant volume. More volume stored in the rad with no change to coolant flow will allow coolant to sit in the rad longer than the 36mm versions. Im hoping this along with a map tweet and more shrouding + reducing the fan cut in temp will help.

Small update on the zed! After ordering a 53mm Koyo rad and being sent a 36mm crossflow hyper V core koyo rad I have done a fair amount of research on what is the best koyo set up. After 4 email's and messages to koyo with no reply I have given up. Feed back from koyo is terrible. Tarmac sportz have been great and have sent me the 53mm core I have ordered so I have ben able to take some pics and measure fin density on both rads. Koyo website sates they do a 48mm core with high fin density but i have not been able to order this even via feedback from the UK supplier!?!?!? 36mm crossflow koyo... After looking into rad design quite heavily this to me looks like a worse design than the down flow set up? Excluding higher fin count 53mm down flow koyo. 53mm vs 36mm 53mm core fins per inch is 13-14. 36mm Hyper V core is 17 fins per inch New mishmoto slim fans needed for the thick 53mm koyo set up Slim fans will be set up so both run all the time at two speeds, the slim set up should allow more room between the fans and the block to allow rad air to exit via the bonnet vents. My AC is now also removed which allows for better venting of the rad with out the AC compressor in place. Abbey motorsport have also sent me a cypher cable to do some data logging I have only had time for one very quick run in the car. I logged the run but have some how managed to lose the log From what i looked at I think the car is running a little lean which will also not help the cooling system load. When i get chance I will also weight the AC system and update the cars dry weight.

OMG... Gearbox envy badly!!

Have you??

Ok fair enough! One thing to mention is us spec rads are 16mm vs 24 iirc for jdm cars! Not sure why they have bigger rad on jdm cars tbf? Water pump will keep flow through the block the same speed only change would be coolant sitting in rad for longer cooling down??

Thankyou mate. Will have to meet up when I'm back on the road. Yeah it's not quite as straightforward as you think. Lots of Z's running 400-450bhp but after that they're rare due to the internal overhaul and all the rest that comes with it. Lots of time and patience needed. I often just thought of getting a Supra with 600+bhp already. Soon be back on the road though even if it is temporarily 450bhp. Twin turbo Z's are very rare and that in itself is a good reason to persevere. Howe your Z? Agree mate, very rare cars built TT zeds. I don't now but i doubt there is more than a handful in the UK??

Good news on this one mate! Glad to see it progressing... the way I look at the zed is its a very long term projects so any set backs ill have to just suck it up and garage the car for a while while i build funds to fix/improve it.

Im overheating on a 36mm koyo too? Im looking at a 53mm version next. I really really doubt OEM would take track abused for creating heat.

Welcome backkkkkk

So after multiple tests on the rad for hydrocarbons horsham test found it?? If the engine is done can you take pics of here it failed?? Also I assume your on a stock block?? I hope my HG has not gone as its a HKS stopper gaskets and ARP L19 studs which are just about as good as it gets ...

Ouch. Im in a similar place. My car runs fine on the road but over heats on track. How much stick would you need to give it to get the oem gauge to move?? I need to hammer mine tbf.

Bump for a few more votes!! 👌

Nice one mark!!

177 is top vote atm... Just need another 28 votes yo take the lead!!! 👌
