This is what I am saying, I am no engine expert but I know a thing or two about sever rod angle and the length of the stroke. Maybe if this engine was converted to Diesel with an RPM limit of 3800.


Keep it simple with the 4G63.

2.0 with a 9.0-1 compression will last you a life time and make all the power you want. Wana get cute? Try a 2.1. Other then that 2.3's are available for a nice street care but aren't all the drag records held by a 2.0?

 

Please elaborate...

 

The rod angle alone would spell catastrophe, meaning with every revolution the angle the rod has to take under a power stroke is way to strong and would put tremendous stress on them.

Second is the piston speed itself, it would be higher then that of an F1 car at 8000RPM's.


If it were a diesel, then year run a ridiculous stroke as the RPM's don't get that high.

 

I've already commented on the F1 comparison...

All the experts in here, yet I am living proof that it works just fine.... Against all odds

 

I am a believer!!!! This is the ultimate street/track motor. Post an in car video of this bad boy ripping through the gears.

 

Just wondering engines HP and TQ cross at 5250 rpm.. what was done to make yours cross at under 4500?

 

Congrats, get some quality vids up, I wana hear that engine note.

 

Haha, that´s funny!



Edit: Cuz you were joking right? The HP and TQ scales are different....

 

You just told us the car has barely gotten any use... Its not like the thing has seen tons of abuse and use.

How many miles are on the motor?

We can argue all day long about the quality of BC components... It comes cheap for a reason.

 

Cheap? that's over 3k for crank, rods and pistons.

Eagle crank/rod and wiseco piston combo... That's cheap! Yet people run tons of power on them....

car has seen 8000 miles so far, no DD.

 

Ok so maybe not real cheap. So FAR your the only person I have seen run this thing, and its not even the standard kit all over.

And you have only reved it to 7500!!! Thats barely enough rpm's to run a mid 11 at the strip much less have any fun with bigger turbo's.

Take it to 9500 like they say and then I'll eat my words and praise the kit if it doesn't blow up.

 

actually NO...for someone into racing you should know that all engines HP and TQ curves will intercet at 5250 rpm. I was wondering why yours intercets under 4500 rpm.

NOTE: exceptions in diesel engins

 

if the units/scale are different eg 10 hp per 10 mm vs 12 tq per 10 mm they will not intersect at 5250

 

that link looks like it is talking about electrical motors and not engines. Math might be the same/similar, IDK. But it is worth mentioning that if you click the other links on the page, that it doesnt talk about Gasoline engines.

 

HP = rpm x T(torque) / 5252

if rpm = 5252, hp = tq
