That's good. If you want to chase a bit more up top the 6766 with bigger compressor is another option, although some loss of spool. Indicative http://forums.evolutionm.net/evo-engine-turbo-drivetrain/605026-new-cea-precision-6466-dyno-graphs-vs-6266-6766-inside.html 6466 does look good in comparison. Plenty of options available. Brian

Good result. At 24lb you're barely pushing that turbo, as 30lb + to get the best out of it. It is rated at 900hp. What is the spool like? That Precision is supposed to spool really good. Brian

Great looking old mans car. Brian

From my notes from 2003 mods. There are a number of exhaust components post turbo in the standard car, as follows: · A single dump pipe off the turbo. There is no splitter inside this attempting to separate mainstream gas from wastegate gas, and probably not required until much higher power levels (I mention this as it is a common mod on rexes) · A 3” down pipe to the cat · A restrictive cat with typical internal honeycomb pattern; 3” inlet with and dual outlet 2.25” · Dual 2.25” pipe to the center section · A center section of dual 2.25” pipe to the center muffler then continued dual 2.25” pipe to just near the rear axle. The center muffler is of straight through design, but is quite effective in reducing noise · A rear section of dual 2.25” pipe which goes into the rear muffler, but the pipe reduces to around dual 2” through the muffler, thereby causing a “daming” effect on gas flow if you want big power. First exhaust mod in 2003 was remove the centre muffler, so done 10 years ago.... then the flood started. Brian

From another thread: For those who are serious, this zeitronix is the gauge to have, showing real-time E85 content. I have posted the picture below in another thread, below from my STi: United I have found to be extremely reliable, with variation between 85 and 87% Eventually hopefully someone will produce an ecu upgrade that will support a full eFlex, for the Ford, without the need for multiple map switching and near tank draining. GMH have a full factory supported version. With my STi, the Vipec V88 ecu that I use can support a full eFlex, although I stay on 85. Ecutek produce an ecu flash where a R35 can use e85 in eFlex mode without map switching, and Ecutek is moving towards supporting other vehicles. I filled up with BP Ultimate 2 days ago, and it was $1.75c/L. E85 was $1.18c/L last week With these relative prices E85 looks good. However, when 98 is $1.60 and E85 is $1.35 it is around the other way. A full eFlex would be the best, so you choose based on relative price, or just stay with eFlex fuel (Caltex) or E85 if you want the extra power. Brian

I was looking for something to quieten the induction noise for my BA intake. Is the car stock? Brian

True, he may be dodgy, but it did work!

However, a BA F6 cluster will plug and play straight into a BA XR6 Turbo. I did it many years ago. Brian

Sydney is a reasonable compromise, as it best suits those from Qld & Vic, to reduce travel. Plenty of Sydney workshops (our advertisers) to chose from if you want a dyno day. The new Sydney Motorsport Park has a new track available for this year, and right next to it is WSID. It is also possible to organize skidpan at SMP also, as plenty of clubs do this. There is plenty of accommodation available nearby, as it caters for large events. Just need to book well in advance. May 2014 will come around pretty quickly if that slot is going to be locked in. Brian

As a guide I did some R&D testing 4 years ago with extractors that I commissioned a 3rd party to build (ETM), the 1st extractors in stock position, with stock turbo, by anyone to my knowledge Extractors had a splitter to stop the gases interfering with each side. I watched the first dyno run after the install, with an overlay against the previous dyno run. Spool was 200-300rpm earlier, but car leaned out ..... this is where you need to be very careful. Car was then tuned. From memory picked up around 20rwkw up top. Tested with stock motor nizpro stage 2 kit. Car ran smoother and noticeably cooler. JP300 also tried extractors and got similar results. Once you go high mount, you can run a much bigger turbo, and good for show. My Nizpro stage 5 has big turbo, but in low mount position, design theory was to to reduce heat. Brian

What ethanol content is your car tuned, since it can vary from E70 to E85. Or are you just using the Rozelle E85? Brian

Best to try to get the time slips for comparison. Generally I'd say you'd want a few runs under both both tyres to get a best run, as it is very easy to have a bad run, or not do something well. Brian

Can you be more specific? Power level will determine how wide and how sticky you need to go. There a big difference between 350, 400, 450 & 500. Good 275 wide rubber on the rear is a better option rather than 245, but you'll need to go 9.5" rim. Brian

Buying flowers is cheap insurance for expensive divorce. It's a commercial decision, especially as I've been married 35 years.... and still get to play with my cars. Brian

It’s all relative. You bought a turbo. Manly people (not from this forum) would argue that why would you ever buy a turbo, when a normally aspirated motor would surely suffice. Many of us go to the drags, or do circuit racing, and really get the most out of our turbo cars, and that’s a different situation. Many of us realize you only live once. Sure we may break some parts along the way, improve them, it does cost money, it’s a hobby, but that’s what we like doing. Going faster is addictive. Do circuit racing and really improve your driving skills. If you want to keep your car standard, that’s fine; my wife’s STi is still standard and enjoyable to drive. Of course you can have a mild tune-up, for a bit more power and better fuel economy, and drivability, without risking the reliability of the engine. There’s plenty and useful information available on this forum to help you. Enjoy. Brian

You have the power! Great mph. Excellent achievement & milestone. 2nd half track is a bit boring when you don't have grunt, but very rewarding when you do. Brian

Good move, heaps of room in it, and plenty of equipment for the money. Although not a ZF, it appears to be a very good copy. Even in manual mode it goes to 2nd gear rather than 1st when you come to a stop. Handles pretty well for its size too. Brian

In terms of your flow testing, what is the band of pulsewidth (in msecs) that you certify the "+/- 1% variance" for all 6 KPM supplied injectors. Brian

Why do you think you need a full 4" system? Unless your are pushing 450rwkw+ a 4" dump and 3.5" rear is just fine. Brian

BRZ runs 11.3 @127mph in U.S. Didn't take long to get pretty quick. Brian

Looks good. What width rims, and what tyres did you choose. Brian

I'm trying to get over the 1.45 60' (amazing), and how you don't get heaps of wheel spin in 2nd. 109.68 at 1/2 track is seriously quick. 2nd half track looks like a long 4th gear pull, as you get around 140mph in 4th with the excellent ZF gearing. E85 has made a huge difference, and amazing what you can get out a near stock turbo. 450rwkw (or just a tad more) seems about right. It all came together and great effort. Well done to Nizpro also. Brian

There was a blitz around Eastern creek again yesterday for World Time attack. I saw them on Cumberland highway with a bunch of well presented cars, who looked like they were in the show--n-shine, and being given a checkover. They were also on Reservoir road just before EC. It's a police annual event. I was pulled over last year. Brian

How many drag runs have you done? You need some practice at launching to get the time down. Maybe reduce tyre pressures. Try different launch rpm. What model/trans/tyres have you got. Brian
