I went in with 158 HP and came out with 172 HP.
But the torque is more impressive.

Have a look:

Chris, Can you print that in English :laugh:

MadMarx

I can translate some words:

PS = HP
Leistung = Power
Drehmoment = Torque
Drehzahl = Revs

Our measurement is based on Newton and Watt

I could be pleased simply listening.

The engine and suspension work on that car this year did make the car 2nd in the championship with 5 points difference to the winning TR3.
224 to 219 points.

And not to forget....still road legal!

You know, that might be my favorite video yet because you're driving on the street like I do. What a gorgeous sound.

Hi Peter,

I have two other daily driver vids:

in this one I drive with straight cut gears and no gearbox tunnel.

Hi Chris,

Thanks for the videos. Not quite the excitement of the Nurburgring but looks like fun over 3k on the street. Nice morning drive after a rain, makes it a little slippery, eh?

brgds,
Peter

Looks good, but those numbers have to be flywheel horsepower. To get a 170+ whp, you're looking at a power peak close to, or greater than 7000rpm.

Torque numbers look great.

172 HP is flywheel power. Wheel power is 120 HP.
But I would say that is good enough for stock valve sizes and stock crank.

As Kas says: Power sells cars, torque wins races.

Stock crank for sure.

Unless you have an expensive gearbox with whatever ratios you need at that particular track :wink:

Sure I run a stock crank - why else should I invent this special split seal ring to fit the stock crank of my engine.

This is with stock seal:

And after installation of the splitseal to the stock crank:

Clean as you can see.

Caused by this

The split seals is installed into the stock aluminum seal halves so that there are two sealings behind each other .

Unfortunately the gearbox has no alternative gear sets.
It is close ratio, but you can change the axle ratio, which I've never done.
If a gear doesn't fit, I drive faster to use the next one :driving:

I meant the "for sure" as an agreement. Looks like the seal is working as planned!

Cause he is gonna want to tear his new, unfinished TR4 back down and start over. :devilgrin:

Just curious, what does a straight cut set of gears cost for a TR4? I looked into them for my TR adapted Toyota R154 transmission and they are about $7500 U.S. For as much as I love the sound of straight cut gears I can't justify that cost.

MadMarx

The straight cut gears fit into the stock gearbox and you can make a choice if you want to use them as 4 gears or 4 gears with J-OD.

I took the OD version.

The gearset does cost about $3500.
You need new bearings, that's all.

Chris
