Im in on a group buy if anyone else is interested! Hey YogiOOO, can you get them for $450 all the time?

I was reading a post yesterday (i think) that said they were $550 retail and $350 trade?

I also read in zoom that you can buy reducers with the Magic cat so it can fit on a 3 inch exhaust. Im not sure if i'd like that though.

Im certainly not an expert, but i thought it was just a measure of the ability of air to flow thru a given space. And as airflow is proportional to engine hp, the more cfm an exhaust can flow, the more hp it can handle without significant restriction. Does that make sense??

Yeah, the air on the exhaust side would be less dense due to the heat involved. So i suppose you've gotta allow for the expansion of the exhaust gasses. Its not that MORE air is flowing out of the ehaust compared to the inlet because the same amount of air going in has to come out again. Its just that the hotter exhaust gas will want to expand, hence requiring more space to flow through without significant restriction. Thats what i reckon.

Oh, i just spoke to the people that make MAGIC CAT on the Northern Beaches (Sydney), and they have come down in price now to $300 each. I mentioned a group buy and he said that he'd be interested in that. Im not sure what sort of discount though. The cats now neck down from 4 inch to about 3.5 inch apparently. I havent heard anything bad about them, so ill probably get one.

SydneyKid has tested this on one of their race cars.

their race cars don't use cats so a dyno run was done as is and as a test he fitted the 4 inch Magic Cat and dyno'd again and the car lost no power at all.

he mentioned that this was the ONLY cat he had seen with this type of result.

Considering the CATCO 3 inch ones are worth about $250 I think, this magic cat at $300 is a bargain.

shif_tea: Depends on the suppliers - Some places we can buy all the auto elec stuff at trade price, but if I were to go to buy their 240 volt gear - we get no discount. (I know as we needed fluro lights for the workshop)

I have heard with places like repco, once your setup with an account with them, you have access to their whole range - although im only going on what I have been told.

Cheers

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
