LOL! I wouldn't be surprised if it does something like that to piss me off.

In reply to corsepervita:

I'm going against the grain here so my guess will be 292.5 haha

I'll go 261 for this test and expect it to go much higher once everything is tuned completely.

254 @ the wheels is pretty good... figure a 10% drivetrain loss and you are 282 crank hp....

A LOT of work went into this engine... BUT the question is how much power. Initial tune 267@ the wheels, with a final tune coming in around the 275 mark

Ok, I'll be the dark cloud. Initial tune around 230hp. Too many new variables on the build so my guess is the timing will be conservative and the mixture rich. On a build this deep, and this new, break-in procedure is more important than performance.

Once all the bugs are worked out, ignition is finished, and tune is stable I'm betting around 295 at the wheels.

269 just cause prime number.

Remember, this isn't at the wheels, this is on an engine dyno!

In case anyone would like a Jalpa of their very own.....On BAT with 67k(!!) miles

I'm in at 302 hp. I'm an optimist!!

I wanna play. 272 initial tune.

FYI there is no "timing belt" on them as they are timing chain. But there is a belt that used a ferrari timing belt that turns the distributor and alternator that is a toothed belt. It provides no mechanical risk to anything like interference motor failure, etc, again, as it only turns the alternator/distributor.

My biggest, most important question to the seller on that would be: "What coolant did you use and when were the head gaskets replaced?" The largest failure I've seen on any number of them has been due to the head gasket material, non-aluminum friendly coolant, the gaskets peeling back, and then the heads beginning the horrific process of pitting. In which case, is a ticking time bomb.

Because reasons:

I'll guess 280 at the flywheel assuming the factory spec is also flywheel.

If memory serves, that was indeed, at the flywheel. I like this game!

263

I wanted 288 but it's been taken twice. So, 289. :)

271 shall be my number. No more, no less.

I've really enjoyed following along as you've progressed here.

My guess is 287 hp.

Some assembly porn. Most splendid.

Japanese gentleman's agreement at 276.

OMG those wheels.

With better fuel control and spark and the increased efficiency of a "better built engine" I will also put the crank horsepower at a nick over 300.

GuessiMofo submits 301.7

Those are silhouette wheels. I'd like to get some myself.

Alright y'all, to make this easier, I've gone ahead and made a sheet with everyone's guesses. We have a couple of duplicates in there. But this will help you see what people have guessed. I'll update this daily until dyno day.
