LSX454 swapped 95 BASS burb.

Little lower, little cooler, bigger sounds.
That was a cammed LS3 if I remember right
 
I'd bet the curves are the same though.
All the cubes are gonna do is move all them lines up farther.

I was wasn't looking at the numbers, just the difference in the curves lol.
The lsxr clearly has a better usable range, to match my power band, than the lsxhr does.

If I stepped up to a 256/276 cam, then this intake would make more sense lol.
 
The dual alt bracket I mentioned would be modified like this.
Then the belt rerouted.Screenshot_20260302-061749~2.jpgIMG_20260302_152724221_MP.jpg


Only problem is, that'd clear the car intakes, but I don't think it'd clear the supercharger. Just depends on what I can get and decide on.
The ls7 heads limit options considerably.

If all else is the same more cubes will not only make more power everywhere but it will also shift the peak numbers a little lower in the RPM range.

That is true, and it turns out that LS3 was 441, which I don't know why they weren't using LS7 heads then, but I didn't look at the article. I remember looking at some LS7 article and it was closer than that I remember, but either way I think it goes back to your first though, is the difference worth the cost if its only temporary?

I would question if you would even feel the difference.
 
I've always been told 30ftlb difference is noticable. Every ones like "that added 30lb...:yikes:".
Maybe in a hoda civic it makes more of a feel able difference than a 600ftlb beast:dunno:

But it does ADD quite a bit in the exact area of my launch, and keeps adding all the way to my shift point, so I can't really see it as a down grade.
And I was thinking, I'm SO close to this thing spinning off, that between adding that torque and power down there, and the new converter , it may just start doing good burnouts.....?
If it does, I may actually skip my dream of twin screws and save $15k. Lol.

It was at the point before the last trans gave up the ghost, where from a dead stop, mash the gas it'd spin enough to know they're spinning, but not enough to let go completely and smoke em.

The extra converter will get me right into where it currently starts waking up . Add that big hump in power at that same 3500-4000 area and I'd think it'd definitely be feelable:waytogo:

Add in I never WANTED this intake, and wanted the LSXR since the start:dunno:
It's only $1300 :whistle:.
I don't need the rails or anything because mine work with it.

Yeah, if I SC later it's kind of a waste. That's true. And in all reality I might anyway just because it's all I've been thinking about lol. But the numbers and amount of work it's going to take to achieve are starting to weigh down the idea significantly.:frown
 
Fug.... That was a long post.:doah:
Sorry lol.
 
Now I have to seam seal the welds all along it, and move to the quarter on the other side while it's on the lift.
Then it comes off the lift, moves over and gets put on tall jack stands.
I'll pull both passenger doors off, tape cardboard over the openings, and weld in the new outers.

I'll do the hinge bushings front and back while they're out.
 
.... Well......
I didn't blow my face off! :dunno:

For that you need to change the intake manifold type.
That's in 'Induction', and it still doesn't give you any option for boost.IMG_20260303_235234986_MP.jpgIMG_20260303_235244321_MP.jpgIMG_20260303_235225384_MP.jpg

I've clicked on a bunch of those and none of them have anything about boost.
I've clicked all over it. I think it's all an NA program. :dunno:.
It has one spot about nitrous. But that's as close as I found.
 
Also tried my engine with a bigger cam.
I went up to a 246/266 , and it only added about 20hp and shifted the curve right just a little. Lost a bunch of torque below 5k.
Not worth it lol.
 
I have an older version of Desktop Dyno and I can select "forced induction" there....

Started on the driver's quarter inner.

Made up this piece last night at work.IMG_20260305_145755529_MP.jpgIMG_20260305_145815122_MP.jpg

Had a couple hrs before work, so I went ahead and put it in.IMG_20260305_154730518_HDR.jpgIMG_20260305_162644161_MP.jpgIMG_20260305_162837200.jpg
 
I always thought there was something missing here, ever since I tore the passenger side apartIMG_20260306_145318475_MP.jpgIMG_20260306_145322830_HDR.jpg

I was right, because apparently it's supposed to look like this lol.IMG_20260306_145301622_MP.jpgIMG_20260306_145257341_HDR.jpg

One more part I have to fab lol. Oh well.

I think I'm going to sand blast this piece and save it. I cleaned it up a bunch after this, and it's in good shape yet. This side will go pretty quick.
 
So... Doing some digging through data logs.
And I believe holley DOES kick the limiter when it senses slip.
Limiter setting.IMG_20260308_054447360_MP.jpg
You can see in this last datalog, at 6300, the rpm (red line) kind of plateaus. Then at 6400 it kicks the limiter (blue spike)
IMG_20260308_054857877_HDR.jpg
Yes im in the process of letting off, but it's clearly still accelerating lol.

On my trans log, you can see it shifts, but the input shaft speed (green line) keeps going up. Until it kicked that limiter and I let off.IMG_20260308_055519019_HDR.jpg
Same type of log with the original trans a year earlier.IMG_20260308_060025004_HDR.jpg
Input shaft speed drops as soon as the shift happens, as it should.
During that run, no limiter happened.

So, HOPEFULLY, it won't happen anymore with this new transmission.
