Yeah got into it today a couple of times and had one massive backfire. Might be over boosting but then again, plugs are just copper v-groove and are a bit old as well as the coil packs which have seen over 6 months so might be time for some fresh ones. I'm keeping off it anyway until I do get it looked at. I heard XForce changed their CAT design at some point to remedy this issue. Apparently the substrate was in it's own case then that case was welded to the CAT body? My system is over 2 years old so probably an older one.

Hey All, This is the latest 1 cpm XForce CAT. Ultimate flow, increased spool and nicer note. But seriously, for the last couple of months, my car has been running like a Holden. Very down on power, low boost and exhaust note had become very quite. I had a feeling there was a problem in the exhaust (genius). Took it to Glenroy exhaust yesterday and found the CAT had dislodged and found it's way into the rear muffler.Cleaned it up, bolted back together and now it's all again Cheers, Steph.

My BTR built by RVO has held 315-370rwkw for 2+ years now and it still feels crisp. It has been setup with a lot of line pressure both in the tune and in the box. It bangs pretty hard when shifting but this has no doubt helped it cope for so long. Also, the AU planets have less teeth and therefore each tooth is beefier.

On some dyno printouts, I have seen 'derived' RPM from a run in a 1:1 ratio compared to ODB 'actual' RPM and the difference in the was 1500+rpm. That thought in my head may have lead me to ask this question that perhaps something else was going on. That's all. No biggy. Still a misssssiiiff effort

Oops, forgot about the fact that it was an E85 tune. That would answer my question. Thanks Brian. Perhaps you misunderstood what I was asking. I am not questionioning the total amount of torque or power being made. Rather, my query was about where it was being made or where it begins to be made RPM wise. It is a legit question. Wether it is due to ignorance, lack of knowlegde or oversight is another thing. That tree is not one I'm barking up

NP mate. Just to clarify what I meant, they are the same quality ovate alpha behive spring. Probably the best off the shelf spring available for our cars. Standard seat pressure at installed height is 95lb from memory. With a shim, they can be taken to 110+lbs to handle 40psi or more. As others have said and as I've experienced myself, Brad has always got time to help you out and point you in the right direction. Atomic have many excellent products and easily the most extensive range for our cars. I'll be using many of Atomic's products in my big-banger including cams, vernier gears, oil pump, race girdle, stud kit and timing chain.

Same springs mate.

Just reading back through this thread and seeing the power and torque curves, the amount of power and torque at such low rpm just doesn't look right. Is the RPM actual or derived? There can be a huge difference. Not trying to take away anything from the car or tuner, Still an awesome result.

I'm using a Bullseye Power S380R for my big banger. As Pat mentioned, they are rather large. The compressor housing is 10.5 inches across although it is rated to 1350hp so I don't mind so much. Snort looked after manifolds and it just squeezes in.

Hehe. Not that he needs backing up but I have to back Mick on on this one. The opposing end tank design is a large part of the reason why these I/C's work so well. I have the early version 2 Nizpro cooler and it works very well. Data logging showed that temps never rose by 9 celcius over start temps. That goes for the 3 times it was re-tuned after fitting this cooler. Last session was after fitting new coil packs and we made 370rwkw @ 17psi on a 30+degree day. They do seem to work very well.

Very nice.

Cheers Matty. I've been on the blower with Geoff a lot over the passed few months and he's got some great ideas that he's incorporated into his latest offerings. Can't wait to see this gear at full song.

Teena lady, is there anything they can't do?

Cheers fellas. Getting closer. Exhaust mani is made from 50mm OD stainless steam pipe.

So am I. Will do Spiro.

Finally the valves have arrived. We can now finish the head and begin engine assembly. Intake is 2mm larger and exhaust is .5mm larger in inconel and both are a single groove. I haven't weighed them yet but they seem very light. Also got a pic of completed turbo manifold, plenum and runners from Snort. They look awesome in the pic. Can't wait to see them in the flesh. The new 1200 plenum and runners have some neat features. Snort Iceman 1200 full replacement plenum to suit EA-AU and BA-BF 4.0 litre Falcons. Solid cast aluminum available polished, satin and powder coated. 2 Piece design, larger volume, 44-38mm tapered runners with shorter intake. Retail is $1299. Great price for this kind of setup with flexibility to custom port the runners as Geoff has told me he's designed them with plenty of meat. They will also suit throttle bodies from stock to 90mm.

Run. Turn around and run and don't look back lest you turn into a pillar of turd.

That, or stick a glide in it

Hey old fart willkommen.

I had a Cox fixed-line plastic F15 with a beasty .049. Used to make us chuck when we shortened the lines so we could fly it in our suburban back yard. Ahh those were the days.

It all depends on your budget. You should be able to do an F6 short changeover (depending on who you know) for around 6k. If your budget allows, either grab a block and do the build yourself with forged rods and pistons or grab something like an Atomic short. Either way, you should definitely do oil pump gears as well.

Sorry to hear mate. Ford retail was about $4200 when I checked about a month ago so $3500 is cheap. If you want to stay with the sameish turbo, you could grab a Garrett 3582. Should be able to pick one up for around $2300 new. Give some of the site sponsors a yell mate. Try Chris at Rapid Systems. The Garret turbos have the high nickel rear housing as well as a larger intake and steel cage for bearings as well as a larger wastegate port and flapper than the Ford unit.

Sorry to say but it sounds like you've bent a rod or two. This is a common problem when running generic tunes without checking vitals on the dyno. Sounds like it leaned out. I bent 2 rods on a 10psi generic tune in exactly the same manner after having my car for only 2 weeks. I only had it loaded for about 45mins. On the bright side, you can take the opportunity to beef it up now. The cheapest option for a fairly reliable mid 300 rwkw is an F6 or post 06/06 short from Ford.

It is cheap and they just might do a great job but I'd be wanting to know a little more. What machining do they intend on doing? I spent about 4k in machining and balancing the bottom end alone, albeit with the intention of 1000+hp.

Nice time. Well done and congrats.
