<div class='quotetop'>QUOTE (REDZMAN)</div><div class='quotemain'>DJ, bro, cut out with the double posts mang. Use the edit button.

One of you mods needs to FIX THEM BOTH.</div>

crappola, sorry bout that mang, wont happen again.

 

Fixed the double posts smile.gif

MAN! THIS IS AMAZING!!! I cant believe those numbers! and the fact that you run stock internals is also amazing!

You got a beast down there!!!

keep us all updated with your project smile.gif

 

Yeah putting down those numbers with stock everything (kinda) is very nice to hear. Really gives Speed-Factor a nice plug too.

 

Here is some useful info posted by Random on HA.com (I copy/pasted it for you lazies that won't get there and rea all of it).

<div class='quotetop'>QUOTE (Random)</div><div class='quotemain'>Here are some average piston speeds for the 1.8L vs the 2.0L based off stroke.

1.8L 85mm stroke 3.34 inch stroke
6750 3758 Feet per Minute
7000 3897 Feet per Minute
7500 4175 Feet per Minute
8000 4453 Feet per Minute
8500 4732 Feet per Minute
9000 5010 Feet per Minute
9500 5288 Feet per Minute
10000 5570 Feet per Minute

2.0L 93.5mm stroke = 3.68 inch stroke
6750 4140 Feet per Minute
7000 4293 Feet per Minute
7500 4600 Feet per Minute
8000 4907 Feet per Minute

10000 6150 Feet per Minute

There is 10% less average piston speed at each RPM. That means less wear, less stress on the bearings, con-rods, pistons, etc..etc..etc...

The rule of thumb for normal passenger cars is that average piston speed should not exceed 4000 FPM. "Performance" motors that the average ethusiasts builds can withstand 5000 FPM. Only Forumla 1 and 100% dedicated race motors can withstand 6000 FPM and more, and those can't stand it for long (only 500 miles at best).

It looks like my limit is going to be 9000 RPM, right about the 5000 FPM limit. 2.0L motor hits that limit at about 8100 RPM.

NO I'm NOT saying that you can take your bone stoke 2.0L to 8000 RPM safely. These specs are for BUILT motors(balanced, blueprinted). I'm saying I wouldn't reccomend you take your bone stock 2.0L any higher than it is now. The stock motor is already over the 4000 FPM "rule of thumb". (Unless you are going to rebuild your motor to proper tolerances).

Okay...now the question is, why the extra RPM?
Simple. GEARING.
Let the chart below be your guide.
