The easiest way to measure the tire circumference is to set a marker on the floor and on the tire exactly above the marker on the floor (a piece of tape will do). Push the car for exactly one revolution until the marker on the tire is in the same position as before, place a second marker on the ...

I've got a question about the power measurement.
What figures do you use for the tire circumference ?

Ive R888 in 225/45/17
If i look at the Toyo specs they give a diameter of 25 inches
so 25 x 25.4 x 3.1415926 =1994 mm

However, in the same specs you can find the number of tire revolutions per ...

Received last Monday.

Thank you again for this group buy

Would this wire extension work ?

Transfer done today.

I'm in !

No group buy yet.
I am just polling interest, and then see if i can get some off the prices (which is allready steep, thus difficult)
Sending to france is no problem; should be about 20 euro.

Keep in mind this throttlebox is ONLY interesting for those wo have done, or will do a speerke remap ...

Hi,

Is this a group buy for it ?

I'm interested if it can be shipped to France.

So how could Anders find 9.5 of valve lift with very close camlifts ?
To me the 9.5 mm found by Anders looks weird.

The cam lifts given by the performance handbook for the L61 are in line with Dude figures:

5.9804 intake
5.9752 exhaust
5.9619 measured by Dude.

So is there a change in the ratio between the L61 and the Z22se ?

The figures i gave are valve lifts (the ratio is around 1.4 but i can be wrong on this).

However, they are taken from the performance handbook for the L61 engine (the american version of the Z22se)

From what i know, standard lift is 10.0795 intake
and 10.0792 exhaust

Thank you Tibby,

Did Peter try to change the ignition timing a bit ?

In fact, i'm not so surprised by your 160 HPwith a stock exhaust.
What really amazed me is the power level of Peter's car with a stock exhaust.

Tibby,

What about the idle with your cams ?
Is it smooth ? Has the idle speed been raised ??
