quick maths here.

say ~600bhp 2 bar absolute means 300bhp NA!
so needs bridge port and custom inlet manifold and BIG REVS to achieve that goal ;)

Hence the benefit of this thread, you can work it all out pretty quick. :Typing
(this is where the list of proven cars on the first page with normal revs and set ups can be your guide to what is achievable)

Doesnt work in the real world though.
You would be lucky to get 250hp in N/A form for that.
Also you need to approx about 1.2 bar to get what N/A would be taking into account that the turbo heats up the air which reduces the actual volume of air.

^That is a common mistake most mechanics make.QUOTE]

I am sorry Peter but you are wrong. It is a common misconception that people fall into the trap of especially on turbo engines due to swept volume being the same but potential on turbo engines volume increases.
When the compression is lower the actual chamber volume increases but the swept volume does not due to the combustion chamber still displacing in one steady revolution the same amount.
Think of a piston engine for example, a low comp piston will be physically lower in the cylinder at TDC which means that it will correspondingly be lower at BDC(Meaning same swept volume), but the point is that when at BDC the amount of volume is greater than a high comp piston in the same engine, the only difference is that because the engine runs lower compression it makes less power in N/A form,but as soon as you a strap a turbo on you have a variable compression ratio once above 0 bar N/A and thats where it becomes exciting cos by running higher boost you effectively can make more power by getting more charge mixture into the chamber. Boost level determines whether this is succsessful or not in contrast to higher compression rotors.

check the Magnecor plug leads,they are notorious for not seating properly!
As Mark said plugs probably need changing too,put 9\'s all round.

Rotary and General Chit-Chat / Pete Barbers write up of EDC WIN!
« on: May 19, 2009, 10:31:52 AM »
Below is Pete\'s write up of the event at Knockhill where he won outright in EDC.

"well what can i say about this round other than it was fantastic, the event was by far my best to date and also my best result.

we arrived at knockhill ( scotland ) on saturday the 16th  to heavy rain and quite strong winds, all the drivers had the same feeling and that was that the event was going to be utter carnage and worst of all no spectators to cheer us on. we had an hour and a half practice session starting at 5pm and this proved to be a challenge as the conditions were not good at all, after the practice and with the bad weather we dicided to get an early night and i\'m sure many of the drivers were praying for better weather for the main event.

sunday came and the prayers were answered, we awoke to find a nice clear blue sky and a glowing sun. the event kicked off with driver practice and new driver licensing at 9am, at first the track was pretty patchey it terms of the large scattered puddles on the racing line which proved to be pretty difficult for many drivers.onto the twin battles

top 16 twin battles,

the twin battles were announced and i had a very difficult competitor, he was the ulster drift champion from ireland 3 years running and was proving his worth in the practice session, the battle went pretty well but my competitor was slower than me through the section which made it tough for me to adjust my driving style to suit, the battle had to go to a sudden death round and that luckily went in my favour as i clintched the victory and progressed to the top 8

top 8 twin battles

i went into this battle feeling pretty confident as i was starting to settle into the car and track layout, i was put against bret castle who was the 2007 EDC champion so was a very tough and well experienced drifter. this battle was once again sent to sudden death as there was nothing to call between us, i knew that this was my only chance to progress further and i had to give it my all. we both went flat out from the start line and hit 94mph at the point of pullung the handbrake to initiate the slide, i kept very close to bret and was pleased with the run but i knew once he was the chase car he wasn\'t gonna give me an inch, this run also went in my favour and i progressed into the semi finals.

top 4 twin battles

for this battle i was up against mark luney in the SVA nissan 350z, this car is truely mental and cost close to 100k to build, i knew this battle was going to be once again a close call, we set off with me as the chase car and this run was very close and the result was a 5-5, when the table was turned i once again had a good fast and clean run but luckily for me mark made a small error and therefore gave me a 6-4 advantage and along with that my place in the final.


by this time i was still in shock and was over the moon with the way the event had gone, i knew that the least that would happen was a 2nd place finish, i felt like i needed to just play it cool and try to put on a good show for the spectators and not spin out. i was against james russel in the DCY nissan skyline, again james is a very good competitor and trying to make his presence known, i went out in the chase run and was glued to the skyline and produced a 5-5, whowever in the chase run i was able to stretch the rx7\'s legs and gained a fairly substantial lead giving me a 6-4 advantage and the win.

this was like a dream come true for me and was a long awaited victory in the EDC,

here are a few action pics from the event,

Cheers Pete"

Sadly Dan I din\'t go,but according to Pete it remained dry yes,but practise on Saturday was wet.
I was at Japfest instead and Knockhill is a long way to go!

Big congratualtions to pete Barber who has just won the EDC drift round at Knockhill this weekend in his FD RX7!:wiggle
Pete is a great driver and had some stiff 500hp plus opposition,but they just couldn\'t keep up!:spank
I am sure that pics and vids will be posted soon.

Best regards for the team here at Hayward Rotary!

Your car is just simply amazing!
The attention to detail at every turn,the more you look the more you see is what serious show car modding is all about.
A fine example.
Thanks for bringing it along.

2 Mitsubishi Mirage\'s came in front of the 350z in 39th and 41st place respectively so were the quickest Japanese cars.

A mini won the class?
How did that happen :s

The car that won in front of Brunswick in the same class was a Lotus Exige that came 30th overall.

Brunswick came 2nd in class and finished 50th overall, they had a few problems,they lost 5th gear and had to do most of the race with only 4 gears,also they changed the diff so had a total of 4.5 hours of downtime in the pits,but they did finish and rang me to say how pleased they were with the engine which has not given them any trouble at all!
Just goes to prove the reliabilty of these little engines.
We done Brunswick.

balls..................... LOL

Oh well, looks like its going off the road for a bit. Too skint to fix her till I get paid again so guess i better find a runabout, certainly dont want to be driving about on my motorbike for the rest of the month in this weather! :eek:

Thanks for the info Carl, will a proper compression test show a chipped tip up ?

Also if you do chip a tip am I likely to require a rotor housing as well as new tips ?

Hi Steve,
A proper rotary compression tester should show it up.
