I dont recall seeing a 2560 making full torque at 3000rpm.

And the CT is gonna be a little lazy at this low boost levels.

You guys are assuming it's a 300hp $50 turbo. It's not. It's a 350whp+ $50 turbo.

I'm trying to figure out how this 10:1 engine can possibly hold together if its indeed making over 300whp and 260wtq and he's doing pulls in 6th gear to redline. I bent rods on my 9:5 engine at only about 250whp and I never even did a pull in 6th. Just sayin

Or the whole hitting MBT on 93 on a 10:1 engine.

Well it is....I can make a video if you don' thrust me but it'll have to wait until march when there will be no more snow

As for why it still hold up I would guess that because it is tuned damn safe regarding timing..

I'm not sure i really buy the numbers either, but the youtube video of how it drives seems pretty decent, despite the turbo not hitting enough boost to even "wake up" yet.

And this was my main "WTF" moment.




OP, mind posting up your timing map?

Except it was 91 octane.

Maybe French-Canadian 91 is more resiliant than US 91/93 octane...

The timing map will not tell you a lot since it's an FIC. The map will only show the amount of timing that is retarded over the stock map at full load like this:
-7 -7 -7 -7
-4 -4 -4 -4
-2 -2 -2 -2
0 0 0 0

If you still want to see it just ask and i'll post it

As for the numbers, the only comparison I can give you is 2 years ago my 7mgte supra at 20psi with a t66 did 470whp on the same dyno......

Must be a leatherface magic block. Maybe OP bought a car with 8.6:1 pistons and forged rods and didn't know it.

Leafy means your numbers don't make sense. Either you'll throw a rod in the next few weeks, or your dyno is reading high.

Props for the vid though.

lol

so you're pulling 7* from the 27* or so that the bp6d ecu runs at peak maf voltage
that's 20* of timing. that's a lot of timing. it doesn't add up. at all.

because if it does, then you just set the record for highest hp stock bp6d

The Escort GT/Protege guys have been running over 300whp on stock BPs for many years now... (Street cars only, for whatever that's worth.)

I don't think this car is actually over 300whp, but i'm just sayin'.


Stock motor @ 312whp


Stock motor @ 339whp (There's other videos of this car around)





Again, just street cars and i wouldn't expect them to hold together for decades, but it's possible in general. I just don't think it's truly possible on this low amount of boost. I'd expect OP's numbers from probably 15-16psi.

yeah i pull around 7*.... and up it to -1 on the dyno to hear a single detonation event in the det cans but power was going down after i upped it from -4*......-7* gave me 1whp less than -4*..
glad to hear I have break the record for the highest stock block bp6d

I doubt any of them are running 10:1 compression and are able to dead hook to load up the engine the way we can, but I don't know. The only fwd bp I've tuned put down 250-270 and ran mid 12's at 110-112

Oh, so you're saying Miatas blow motors because they dead hook in 5th and 6th gear, unlike what a 300whp BG car would do? <3 These guys are doing deep 5th gear pulls, mostly because they're retarded and feel like going 150mph+ in a shitty 20 year old econobox is a good idea.

The compression is secondary to your argument. Stock rods is stock rods.

I don't remember what compression my BP05 was. I threw it in the trash because BPs make my ***** soft.

I said I don't know. I know that the festiva I tuned was never able to hook 1st or 2nd, and by the time it got to 3rd-5th it was well past peak load and operating in the 5-7k range. Find me one other 300whp 10:1 bp6d that held together for more than a few dyno pulls and didn't splooge its internals. That's all I'm sayin

What rpm was your peak torque at in the 9.5 motor you bent rods in?

Maybe the reason his hasn't bent/thrown a rod yet is because his peak torque isn't until 4000rpm?

Based on what little engineering knowledge and engine knowledge I have, I think 220wtq at 2800rpm is harder on the rod than 220wtq at 3500rpm.


That said, everything about this thread makes me think this engine is living on borrowed time. It's hard to believe he wasn't hearing any knock on 91 octane, on basically the stock timing map retarded 1*...

It was a gt28rs sized turbo (hks gt2535) that hit peak boost at exactly 3500 actually.

I know what you're getting at and I agree, but from his plot this turbo doesn't look all that lazy at all. Looks pretty darn good actually. Whether the plot is optimistic or not is a different question, but I'm pleasantly surprised with the ct26 in this case. I'm guessing the custom tubular mani and ewg are helping a bunch

He's using the factory internal gate, which is probably just fine at these boost levels. I have a hard enough time keeping an EWG shut when i want it on my CT26. My solution was to stack 21psi worth of springs in the gate.

If only your valve springs were stronger than 21lbs you would have been OK
