Assuming you shift at redline in a 1/4 mile race what is the entry RPM of each gear as you shift through all the gears?

Example:
When you are in 1st gear and punch it all the way to redline and then shift into 2nd gear, what is the new RPM as you enter into 2nd gear?
What is the entry RPM for each successive gear assuming a shift at redline each time?

Is there a table posted in this forum?

Thank you,
Tony

You have PM!

Tony,

max mph in each gear (approx.):
1st --- 42 mph
2nd --- 69 mph
3rd --- 99 mph
4th -- 126 mph
5th -- 161 mph

1-2 shift ==> 4600 RPM
2-3 shift ==> 5200 RPM
3-4 shift ==> 5900 RPM
4-5 shift ==> 5900 RPM

Thanks for the gear info guys. I'm working it into the plots now.

Motordyne · 11-20-2010, 09:28 AM

OK, I have the gearing and shift points worked into the plots.
1/4 mile racing deltas have been worked in.

Has anyone datalogged their RPM's during road course racing?

Nice data --- need your ART pipes before I think about using the redline regularly on this vehicle.... stock cats and this Z does not like >6500 rpm realistically.
Interested to have this and the ART pipes on, I like to have a punch right where you want it.

Staples · 11-23-2010, 12:12 AM

This mod is good in increasing gas mileage too.

Great data, Tony!

I have now put a 1000 km on the new Motordyne intake and my 370 z. I gave the ECU time to ajust. I also ajusted the fuel curve as it runs rich at top end. I also made a few small ajustments to the fuel curve using Cobb. My car has every bolt on + 4.08 gears and it is a 7 AT.
It is way quicker now. I shift at 7800 rpm. 1st and 2nd gear are so quick that its easy to hit the 8100 rpm limiter. ( there also is a 200 rpm error on my tack. It is read to low at high rpm.)
The aceleration is increadable. Tony has my dnyo of the car and im sure it makes more power now. It also a very deep sounding growl to it now.
Some young guy with an Audi A3 had a go with me and lets just say in the first 400 ft i blew him away by a mile. It was a 80 km speed zone and we took of from the lights I lifted at 100km. Ive been to the drag strip many times and the car really is a lot faster now. I have no traction issues as i have 305 35 18 tires on the rear of the car.
It to bad that the track are closed up here now as i will have to wait till next year to get the 1/4 mile times for the car.
I expect to get my GTM stage 2 SC some time in 2011 and i will ge trying the manifold on it .

Would be a million times better if you could put stock engine cover back on.

You can.The stock manifold has two stud bolts holding down the rear end of the back cover, just use two 10mm blackened bolts and your are in business.As Tony said in another thread you can order the manifold without the Motordyne plate.

Stock engine cover fit fine over mine.

Kastley85891 · 05-01-2011, 08:26 AM

Mine arrived yesterday and as usual from MD, well packaged and uber quick FEDEX, (delivered on Sat, nice) starting install today. ;-)

What are your 60ft times and are you running street tires, drag radials, or slicks? Thanks
