seeing this gives me hope I will get my stuff straightened out. huge congrats....
question tho, did u ever swap ecu or are u still stock

 

Still stock. Although it is getting damned difficult.

 

and speed density u said in first post, thats,still true? what have u found difficult as far as the stock ecu

 

I actually just sent you a PM.

If you are going to run SD, it is best to do the custom OS. What is making it harder is I am bumping up against Ecu maxes so the tune is scaled and that affects a lot. Meaning I have to constantly keep calcs in my head making tweaks.

Also the aftermarket stuff will learn off the WB which would be great as well. And interface with custom gauges. My tach especially sucks. I can rev and shift and the needle is still going up after the clutch pedal goes in. Stuff like that.

 

I'm so glad everything has worked out well so far.
From the beginning of this thread and all the carnage that came with it to what we see now has made it worth the wait.
How many people can say they have an 800HP NA car that still drives well?
It's rare.
This is better than anything from the DOHC exotic supercar segment.
I don't know of any that make this much power NA.
Even if they did they would need to rev further out and the overall driveability and reliability would not be as good.
Darth, I would never ask for you to hold your phone and do an acceleration shot. Lol
That is way too dangerous. You would either need a passenger or a go pro mounted on the dash.
Keep us updated on the fixes and it would be great to see it clear the 700rwhp mark.

Also a big shout out to Tony for having a great product that works so damn well.

 

Thanks Bort!

I actually used to hold the phone to the dash all the time. Will definitely keep it updated!

 

So in summary here same dyno to same dyno 75 hp and 50 tq and the two main difference were a camshaft change and Mamo 265 heads. We know the heads (old ones - stock port lingenfelters?) but - What was the old cam to new cam change in specs? Both solid rollers? Very nice flat tq curve from 5000-6500 rpm. A 100 point delta between hp and tq is great. Of course we have the follow up numbers which are even better but I was just stick with apples to apples. I would agree the full exhaust is probably hurting you after like 5,500-6,000 rpm. The info may be in here somewhere in the 65 pages but thought I would get the summary.

 

Yup. Old cam was 248/255. New one is 256/270. Both solids.

Even the 75/50 is not quite apples to apples because the low number was on radials and the high number was on slicks. So the true gains were higher. Something like 95/60.

As far as exhaust it is uncharted territory for me. I am pretty sure the exhaust is hurting a bit just unsure how much.

 

That's wicked. And still breaking in and on a stock computer too. Fix that #3 oil issue and let it finish breaking in and it'll hit 700. As said, IDC don't lie and yours didn't! Thoughts on the #3 leak? Valve stem seal or guide? I forget, did the c.i. increase too from the rebuild or just H/C?

 

It went to a 440CID.

 

The difference in power is great but the I bet the driveability and the way it runs would be a TON better than before compared to his old heads.

 

Awesome Jaik, thats a ton of power on tap. Congrats bro!

 

I drove the old set up and it drove fine. This new set up just has meat everywhere. The old set up was flipping fast and the new set up will be nuts on the street. People don’t realize just how evil this kind of power is in a daily driver. You have to be on your toes all the time and especially when the next cryote mustang thinks it wants to try and you down shift to 4th at 60 because third won’t be needed LOL I’m so happy for Darth. This has been a heart breaking adventure from the beginning to now a I can’t believe this animal. Chevelle, Mamo and Darth equal a recipe for greatness imo. Congrats brother and I can’t wait for the first track outing. I’ll be there if given enough notice for sure!

 

Could you do it with a phone mount on the dash ... start the video, look for cops down the road and in mirror, put both hands on wheel, floor it for 5 seconds, done. Anything this fast can only be floored on the street for 5 seconds anyway. :-)

Congrats on the nice result.

 

What I like is it appears he picked up some low end while going to a bigger cam. I guess that's the 265 cc head with big flow helping out there. I think the lingenfleter is like a 275 cc head or so. I am also wondering is this where Tonys exhaust port is helping out - everybody over looks the poor exhaust port but it is important. How many ccs is exhaust port? OEM is like 87 cc.

 

Part of it was the sniper low profile intake I think was killing torque badly. A lot of the torque gain imo is runner dynamics.

 

Absolutely crushing it man congratulations to all involved! That is a huge accomplishment especially through that drivetrain.

I hope I can get even within 10% of you here. Even with proof in front of me of what my engine should do I’m still skeptical every step of the way. These numbers are so unreal to me from such a streetable engine.

The MSD is doing serious work above 7000 and continuing to pull. That power curve is what I dream about. That plateau up top is just incredible. This isn’t an engine that is just going to put up a dyno number this thing is going to accelerate, and hard!

 

Congrats on the outcome! Not gonna lie I’ve been checking in on this thread multiple times a day waiting for updates! Love the end results it’s amazing. But I have to ask.... what is next lol

 

Draggy video on the seat so we can hear this thing

 

I agree. Once properly sorted (the fouled spark plug issue) this will be a wicked n/a street car. I'm thinking of traction difficulties though.. same as with your 434ci and your car. I think if we ever get out of this covid lockdown, a chassis shop and tubs are in order. I was thinking of doing it to mine before the covid bs began. Darth could probably do a whole custom 1/2 chassis rear clip on his car with some 31"x18.50" hoosier QTP tires under there and not get hassled by police over legality like we do over in australia? Imagine all that traction on the street from the hit....
