This plot shows the difference to my previous setup with the 569bhp run. It's now becoming clear why I'm struggling for traction more than before. An extra 100lb.ft at 4200rpm is bound to feel a little sharper and upset the rear tyres!

wanted Alloy Wheels - 17" or 18" - 10.5" or 11" Wide Rear

What sort of spec were you at when you tried the 315 PS2's? Were you pushing loads more than my 621fwhp and 590lb.ft...... I'm wondering if they might be good enough for me? Surely they've got to be a big step up from my 285 Rossos. The Avons sound great but I think something like the R888 or RA1 would be as extreme as I'd go on the road. Where did you get your RA1's from? Did you ever come across anyone that sells 315's for a 17" rim anywhere? Thanks James, I might well take you up on that mate. Are these the ones I narrowly mssed out on from someone here a few months back? -

The 35 is for grip, comfort went out the window a little bit when I fitted the Titan anti roll bars. I have been running a 275/35 on a 9.5 for the past year or so and I just lived with the lack of grip in 2nd and 3rd gear - 4th was always ok in the dry. About two weeks ago I changed to a 285/35 on a 10" and gained some grip in 3rd gear which is nice but after the remap the other day I am back to square one! I'm thinking and hoping a 295/35 in a normal tyre might be enough to restore some grip in 3rd....I figured I was being greedy wanting to give it 100% in 2nd but perhaps I should set my sights higher What I would really like is a normal 315 tyre (315/30/18 Pilot Sport PS2 is available at sensible cost) on a 17" or 18" rim at something like 11" wide but there's no wheels around. The next step down the compromise list is a 295/35 on a 10.5" but maybe I'd be selling myself short there -
Whoops - just asked an obvious question. I'm heading out to check what type of diff I have

sold 18" Volk TE37 Alloy wheels and R888 tyres
dandan replied to RobSheffield's topic in Parts for Sale
Rob - I am interested in these mate but am just trying to work out if they will be wide enough and if the offsets will fit ok with my arches. I'll be in touch -
Did you order them yet? I'm thinking about selling mine and spotted your post! 18x8.5 35 offset 245/40 Eagle F1 18x9.5 30 offset 275/35 Eagle F1

I think you're right. I've got two sets with 9.5" rears and one with 10's but I don't really want a 295/35 on the 10". Did you pursue the wheel widening any further? -

With my new found wall of mid range torque I am struggling for grip a little with my 285/35/18 tyres and would like to track down and try something wider. I'm thinking that a 295/35/18 (not a 295/30/18) may be enough to get me some decent grip in 3rd gear and above so I'm after some wheels that go to about 10.5" or 11" wide at the back with a 45-50mm offset. I suppose the front would want to be about 9" wide with about a 40mm offset. Anyone got anything they're looking to sell? I'd be happy to try some 17's as well but still need at least 10.5" at the rear. Cheers Dan

Thanks Chris. At first we didn't think my sensor was working so we gave up with it and didn't pay any attention to that parameter. As it happens it was actually working but when we were trying to get some readings there was no real pressure so the signal was lost in the noise. Duh! After we finished all the mapping and reviewing a couple of logs Ryan noticed that it had been reading and logging the whole time which was good news. He's sending the logs over for me to have a look at so I will keep you posted.....

It probably is Wes, I think your car was probably the most powerful up until now with a cast manifold. I know it can make more at the same boost with a few tweaks here and there so there's potential left in it still. The key is in the EGTs and managing the back pressure to keep it all flowing freely. I've been hunting around for other dyno plots with the 67DBB on stock cams and the only one I have found making more power (on any manifold) was Jamie's 630bhp run but that was at 1.8bar and also with the Greddy intake. If I'd have thought about it a little more yesterday (and not been as concerned about having any problems so far from home) I'd have asked Ryan to bump it to 1.8bar so I could compare the curve to Jamie's. I had plenty headroom left on the injectors and everything else was fine but we were also a little short on time so we wrapped it up at 1.7bar. There's always next time I suppose but to be honest - I was more than happy with what we achieved yesterday anyway. I definitely need more tyre on the rears now! I would like to try some cams just for interest sake as I am intrigued with the cast manifold setup I have and would like to see how far it can be pushed without any meaningful restriction compared to the tubular alternatives. If it nets anything like the same gains as you then we’d be throwing some very interesting numbers around! But like I mentioned, I love the driving characteristics of the stock cams and am happy keeping the revs down a little as I don't want any disagreements with my rod bolts anywhere down the line. I will probably succumb to the power bug eventually and stick some other cams in once I have my head around the manifold pressure relationships a little better but the Greddy intake will most likely come first. Thanks mate, it really does drive great and it can be sedate and quiet or violent and loud depending on the boost and exhaust valve settings. No problem at all mate

If they fit and you have all the clips and silicon couplers ready I would go with your new ones and not give it a second thought If you make some big changes down the road for more power then you could revert to the 3" - otherwise sell them and get some money back
-
Very nice. Must be a hoot on the road with that kind of torque curve.
-
At your power level a 2.5" pipe diameter would be fine. Is that roughly what your new ones measure?
-
The boost control is rock solid and stable at 1.5bar. Is that the stock ECU or Emanage controlling that?
-
Thanks for all the comments fellas Treadstone - but with a lot of internal modification. My brother may have got a few vids on his phone, I'll check today. I don't think there is anything to gain in the ECU as I have a Syvecs which already has extremely precise and fast control of the fuelling, ignition timing, and boost solenoid duty cycle. It also has very fast and sensitive knock sensing and closed loop feedback to the individual cylinder ignition timing. I'm 100% happy with the ECU and its capabilities and I reckon I'll be even more happy once I get my head around the logging functions.
-
I have a spare shroud and I think it is pre-facelift. I'll compare it to my facelift one and see how they differ.
-
I have given a cam change a lot of thought but am still undecided. It sure would be nice to see exactly what difference they'd make but at the moment I'll be sticking with the stockers. I like the fact that I don't really have to rev it to make really rapid progress and more revs = more wear at the end of the day and that's the main thing putting me off. I do still have the Greddy intake and Q45 throttle body sat in a box so I should fit that first - maybe a winter job I've also got a nice brand new BW turbo to trytoo but after today's result with the old T67 I'm not sure if I want to go with the hassle of swapping turbos and tweaking maps so that could be for sale shortly! Plus I don't think I need any more torque
-
The 569bhp was at 1.6bar so it's not all boost I had my exhaust manifold pressure sensor plumbed into the Defi's EGT spot in the manifold so the EGT gauge wasn't connected Si; I'm not sure what sort of temps it would have been reading. However, I did have my faster acting thermocouple fitted in the other spot in the manifold and that was the one feeding back to the ECU all the time. Ryan is going to send me the logs over so I'll take a look at those temps and let you know.
-
Yeah I'm very happy with it all, especially the monster torque figure and general bottom end grunt. It's a wide curve too so it pulls like a train in the lower revs which makes for nice driving It made 569bhp before and I think it was 538lbft of torque. Since then I have added my free flowing switchable 4" exhaust, Greddy 3 row intercooler and created the airbox. The wastegate is still recirculated into the downpipe too.
-
And that was 526.5hp at the wheels

Well after a bit of a slow start we got to Surrey Rolling Road late morning today and met up with Ryan to see what my latest round of mods yielded. This is with a Syvecs ECU, cast manifold and Precision T67DBB (not a billet version) on stock cams at 1.7bar. Suffice to say I am happy with the end result Many thanks to Ryan - top job mate, very much appreciated
