A few performance questions

[Brett]

Took the Egi out on the weekend, went as well as it always does even managed to have a bit of fun with an Audi TT, anyway I digress.

 I\'m still getting an odd flat spot at 3800rpm, is this the secondaries playing up or an earthing fault or is it ECU related? (Still running stock ECU)

 Also, are the TII injectors and Fuel pump of a higher rating than the Egi equivilants?  (May still buy Stu\'s pump if its going to make a difference)

 I\'m going to try and squeeze 230bhp out of the block when I get my Microtech..... (if 230 is possible)

Thanks chaps!

according to the yank forum,im sure the hesitation is an earthing problem - but im not 100% sure

and the fuel pump - no idea - a TII pump should be good for 200 - 250 bhp - he says - im sure someone will prove me wrong !

[Brett]

I was fairly certain I\'d heard it could be an earthing fault as well, got a feeling John(88GTR) said something about it awhile back..?

[grinder]

im sure there is a sticky about it on the yank forum //www.rx7club.com

have a look there

[Brett]

Ta, will have a look!

Hi,
Re-earth/use extra earths under the inlet manifold between the 2 sets of injectors. Try and get as many earths between the chassis and the blok and ancillaries. The egi secondaries are bigger ,@ 620cc i believe. TII fuel pump is crap anyway, and wouldn´t use that as an upgrade. 230 is possible with a bit of work;)

Thanks John!

 Does anyone know where I can buy an earthing harness?

[Brett]

So you\'re saying the Egi actually has larger secondaries than the TII as standard?  Or are they just bigger than the primaries?  I looked long and hard at my injectors and never saw any external differences....

[grinder]

im sure the TII are 550\'s

and there is something to do with low and high impedence

[Brett]

Hmmm..thats pretty interesting.  Will have to look for an earthing kit or make up my own for sure, if problem persists then I\'m going to use it as an excuse for a microtech!

Easiest to make your own... and cheaper. Use about 6mm thick core with the earthing eyes.

Think I\'ll do just that, oh the joy of a company account with every component/tool supplier you could think of......

[grinder]

ohhh you lucky lucky man - if you manage to accidentally order one extra of everything - you could post them to me

[Brett]

When I\'m next in the UK I will make one up and test it out.  Assuming it works it should cost around £5 to make.  I dont mind doing some drawings and a write up on what I have done, and yes if I get the time I will make you one too...

 Who knows, perhaps I could start a small earthing empire.....

there are worse ways to make money !!

look at si - rather than buying a body kit - he wraps his car around summat and then gets the insurance to pay for it ?!??!?
