You don’t need the the 2600 to put out more power. Laynlo is running over 700rwhp with the 2300. No engine mods...just more fuel. Regardless of blower, if you want 600rwhp, you will want to run 9-10psi...problem is, Ted has posted some really great data on the fuel system and basically, we see the hpfp dropping off in the 575rwhp range.

On mine, we had more power and dialed back timing to keep it safe until I could get my next round of mods. As an example, the Jannetty Super Street Brawler package is going to put down 725’sh to the rw with the Maggie 2300. You can go as high as you want to go if you just want to pay for supporting mods. In other words, the blower isn’t the limiting factor.

I make 780 with e85 methanol, cam forged pistons long tubes and full lt4 fuel upgrades. I’m at 11psi for boost going up to 14 hopefully end of the year. I wouldn’t go above 650 with stock stuff though every car is different

I am aware that our cars are limited due to not having forged pistons. I would like to NOT get into the internals for right now, and stay within the limits.

I hear different numbers on that - is it 600 hp (ish) to the wheels??

I have a '17 SS 1LE and debating on whether I should just go for the LT4's upgrades right now or later (OR ever?)

Not a big racer, more for street driving, and love the car as is BUT want MORE POWER just because...

Thanks in advance!

If your not gonna upgrade the pistons anytime in the future..... then you should just do the LT4 Blower. I got my LT4 conversion for $4500 from WeaponX.

Nice!

I suppose the alky injection could be in my plans too, but more than likely, I will stick in the 725 range and maybe have a tune for running 800rwhp at the track. I do like the idea of a 9 second time slip for a vert.

Because “not gonna”, speaks to intention before the addiction hits. Once it does, you will need to go bigger. But in theory, you are right.

The lt4 fuel stuff is only good to a certain point. I can go to 12lbs no issue after that time to start looking at fueling options. I would love to be at 800 with just 93 but gonna need some work to get there.

I will be upgrading to the LT4 Injectors and pump, also. Can't do the pistons right now, but hopefully by next year!

Piggy-backing on this thread. I’m installing my Whipple and the supercharger belt seems too small.

Can anyone confirm belt size on the 3.625” pulley?

I just got mine together today. It had a 3.500 pulley on it though and I thought the 3.625 was stock. Even have an email from Alex at Whipple saying the 3.625 was stock and good for 9.5 lbs of boost. Guess I will be getting more boost. I also did the LT4 HPFP and injectors which required a billet rear case to clear the LT4 pump.

I am not with the car right now or I would give you my belt size to compare. My belt with the 3.500 pulley just fit.

[1le32907]

3.5 if I remember is good for 8-9 lbs I’m down to 3.25 and at 11 but that is also with a big cam. Please invest in the green belt

Belt solved, thanks Rob. Have to leave the idler really loose.

Anyone else find that their Filler Tee to Tank hose seemed a tad long?

Yes, seemed a little long, some seemed a little short as well. That was probably the most confusing part was towards the end attaching the hoses. Since not all hoses were provided new, and you had to use some stock hose portions or fittings. but overall the install went well.

I know this is a late answer but with my 3.500 pulley I have a Gates K100816 belt 1-3/8 x 82-1/4 OC belt.

[Jhunsberger]

So per Whipple my kit should come with a 3.625 upper pulley, but the weapon X spec'd group buy part number comes with a 3.500.

The newer rotor design (which i have) should have a 3.625, previous kits had the 3.500 pulley.

Has anyone measured actual boost pressure with your setup? (which pulley)

Whipple says 3.625=9.5psi, and a 3.500=14psi. Both these numbers seem hi to me. I do have a boost gauge (P3 multi gauge with the analog boost) installed, so in the end I will know for sure what its actually doing. 14psi scares me on stock internals though.
