Guess my HP? Full send
 
This Thursday my car go boom boom.
Finally time to take my shitbox to the dyno.
​​​​​
Been running turbo for almost 6 years and running a 2560R got myself some bendy boy banana rods.

Forged rods
Oem pistons from another engine
Boundary oil gears
Toyota cops
Revent welded log manifold
Pulsar 2867 gen 2 (Chinese photocopy)
ID 1000cc injectors.
Walbro 255lph

Using external gate welded on turbine housing.
Going to bring 0,7 & 1bar springs and using both ports on wg (theoretical boost above 2bar possible)

Not going to keep any numbers low since I want my 5 speed to grenade itself, going to weld my own BMW 6 speed this winter (if all goes "well")

WI'll be running 98 octane (93 for you local muricans)

Guess where this train stops, aka what will go south first 🥉

308whp (Murican)
334hp (Eurinflated crank guesstimate)
at 20psi

Sixshooter is right in the ballpark, I think you are going to be knock limited to right around that 300-325whp (depending on dyno)

I dunno the HP, but I like that compressor preoiler.

Strike!
I know, I had a similar homemade catchcan before but i broke, and I need to redo the AN fittings because I'm retarded and went straight up so the contacted the hood. Will weld some material so I can bolt my cops directly on the cam cover also.

Lol. The choke point were my ms3 basic with a 250KPA map sensor.
I love the torque curve the most. Really a whole new car just tuggin around town also.
Will come back with flex sensor, E85, new fuel pump and fpr. Maybe some better coils also then we shall pass 400.

Yes this is engine hp & torque. Before & after. About 21 psi.

My guess was good for 20psi. I'm sure that's a fun ride.

I wouldn't call it good, I'd call it spot on.
Yup sure is, except I blew a Toyota cop when going home.
Bought 4 new (used) ones today 💯

I'm running the LS2 truck coils from the junkyard and they have been good for years if you have more failures.

Dr.Sep Oct 25, 2023 10:08 AM

Maybe it is just the angle, but does it really nose dive like that at 6500rpms? If so... why?

kenwo91 Oct 26, 2023 01:24 PM

Tbh I dont know?
Yes it does really.
