GTSBoy Posted January 25, 2022 Share Posted January 25, 2022 Just extend the reverse cowl in perspex up over the windscreen and roof so it sucks instead of blows.

Funny story The above added ventilation has increased my IAT by 5°c and my coolant, which typically sits at about 90°c, was at 97°c After doing some hasty wool tuft testing, it seems kow when at speeds over 40kph the reverse cowl works very well at sucking in air, pressurising the engine compartment, and reducing the efficiency of radiator stack quite well I assume my trans temps would have raised as well as the air to oil trans coolers efficiency would have been effected as well So, lucky I have the spare bonnet that will be getting the frame modified to give me some clearance Marks bad idea #943: Fitting a reverse cowl scoop LOL 🤯 lol pics of driving around with wools stuck to the car or it didn't happen 1 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960302 Share on other sites More sharing options...
Kinkstaah Posted January 25, 2022 Share Posted January 25, 2022 What else did you think it'd do? It'll let heat OUT of the engine bay when you're idling/sitting but that is about it, at speed the pressure will force its way in. The vents to reduce heat are ones you see on GT3 style cars. The concept is you provide a good ol duct for the radiator at speed for it to the immediately exit, the reverse cowl would probably work if there was a duct from your radiator directly to it and out of the car but fitting that could be.... problematic.... 1 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960310 Share on other sites More sharing options...

I wish they made a bonnet for mine like the vented one I had on the 33, that worked a treat As for the the cowl sucking in air, yeah I new it wound do it, but I didn't think it would effect the IAT and coolant temp so much, with only the 5x 100mm ○ holes it wasn't noticeable, but after the chop chop, well, it's farked After a drive today, the IAT got up to 70°, that is a 20° increase to what it was 2 days ago doing the same run, and the coolant never went lower than 97°c I checked the WTA intercooler pump, and the thermo fans because I thought that I may have invertantly unplugged something, but no, it was all because of stupid Luckly the car is going into the paint shop next week to unfarkithe bonnet #Duncan the "wool tuft" was actually fluoro pink string line, it was magnificent 👌 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960319 Share on other sites More sharing options...

It's noticable when cruising, I haven't launched or laid 11's yet though The car is going in to get the trans shift points played with to suit the new gears next Monday Monday afternoon will possibly have a launch and skid involved.....or 2......for scientific research purposes of course I'm going on a 600km Hwy run on Thursday, I'm curious if there will be a noticable difference in L/ 100 km, not that it's important, but currently it's around 11L=100 km on the Hwy ATM Hopefully hit WSID on 02 Feb, seeing if it helps the 60' a bit is the big one I'm looking at 3 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960367 Share on other sites More sharing options...
robbo_rb180 Posted January 27, 2022 Share Posted January 27, 2022 That drive will be good to see economy.

The Bogan Posted January 31, 2022 Author Share Posted January 31, 2022 Lowered engine mounts are on their way So with the bonnet frame clearanced and the lowered mounts (13mm lower than stock) but with a 5mm spacer so the headers clear the K Frame, I'll have heaps of room under the bonnet for the thermal spacers and underbonnet insulation without have speed holes in the bonnet In other news I recovered my Harley seat with some marine grade vinyl after thinking that tying on a steel tool box to it to take some tools over to a mates house was a good idea, it wasn't and the seat ended up with a big tear It wouldn't win any prizes but at least it doesn't have a hole anymore 1 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960545 Share on other sites More sharing options...

I'm not sure how to picture driving a clothes dryer. A washing machine maybe, but not a clothes dryer. Poly mounts are stiffer, so more vibration from a rumbly V8 on idle? 1 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960626 Share on other sites More sharing options...

I own a machine that doubles as a dryer and it vibrates considerably more on its dry cycle compared to its wash cycle lol. I have OEM Nissan mounts in my R34, and I feel the LS rumble noticeably when stopped through the seats, _BUT_ I believe I have a larger cam than @mlr. My only other experience were poly mounts with a SR20DET which definitely felt like sitting ontop of a washing machine/jackhammer at the lights, i.e it was shit. 1 Link to comment https://www.sau.com.au/forums/topic/480074-mlrs-bogan-cruise-ship/page/30/#findComment-7960638 Share on other sites More sharing options...
