So it trapped 130 in 3500 DA on the time slip?

129 and change - dont have the slip. Video running earlier in the afternoon at 125.

I have to admit - seems like I am getting trolled?

If you were close to 800 rwhp you'd be trapping in the low 140s. When my car had the 2300 it was making 770 and trapped at 142 and at 850 plus 149 was my highest trap speed but averaged 146 mph. When mine trapped at 129 to 130 it was making mid 550 rwhp. No trolling, just seemed a little high with no dyno numbers.

Again - these times and speeds are at my previous configuration, at 700whp (car dyno'd 702whp)

Changes since then are forged internals, cam, headers, more fuel and more boost. When it was on the dyno in March, it was making 740hp with boost at 10lbs of boost from 5500-6800rpm. Current configuration is 3+more lbs since it hit the 740 number.

My statement is that the RE-71s hooked well at the 800whp level, which they do. Ran some digs last night, and the car launches spectacularly.

Yep - we all get it. If it's not a Maggie its garbage.

Now first off, I think P/C makes some good stuff. The F1 is the benchmark for "street" centrifugal blowers IMO. With that being said - P/C and their dealers will tell you that you can get a blower for your car at about $6k. With this configuration, you are getting the P1SC blower, a tiny intercooler, and a bypass valve setup that leaks air when closed and under boost. This configuration had problem never been sold, as people end up buying the Stg II air to air intercooler and the upgraded blow off valve. This configuration would be the absolute bottom basement setup one should consider as it has the proper amount of intercooler for 12-15lbs of boost, and it is not going to bleed off that boost as it has a capable blow off valve (that standard PC bypass valve thing is not very good). Throw in black powder coat for everything (so it doesn't look like garbage in a year) and you are looking at $7400 before any kind of tune (PC only has a canned tune for the very bottom basement configuration).

And at this $7400 price you are getting the P1SC - which is plenty reliable, but is really at its max output at about 650hp (however you can go up to D1SC for another $250 - which I would highly recommend). So $7650, then budget $500 to tune.

The ECS kit is kind of a weird setup - it is a Vortech mounting system and is the same mounting setup that Vortech uses in their kit, however the difference is the blowers. The Vortech uses their V3-Si blower, which is a bit of an upgrade to the P1SC that P/C uses (1150cfm), but if you buy the kit from ECS, it gets a Paxton Novi 1500SL (1450cfm / 850hp) blower.

The advantage here is that with the smaller blowers, they can hit that 700+ mark, but they only flow that air when they are at their absolute peak RPM. You really won't feel the power until 5000RPM on up. The D1SC from P/C will come on a little lower, the V3-Si lower yet, and the Novi 1500 even lower again. The Novi 1500 at 9lbs of boost will make 700whp with room to grow, and will come on crazy hard at 4000rpm.

Now - to talk about the advantages the ECS kit has is that the mount is bullet proof, easy to install and work on, but the big advantage is the belt setup. See, the P/C uses a big long belt that goes from the blower all the way to the crank, with a long arm tensioner to keep it tight. This setup is known to slip at 8-10lbs of boost, so they recommend going to their 10-rib belt setup if you plan to do any "real" kind of boost, which adds $400 to the bill ( we are now over $8000).

The ECS kit uses a jackshaft - on one side of the jackshaft is a 6 rib pulley that is driven by the stock accessory drive. Though it is only 6 ribs wide, it wraps the belt around about 70% of the pulley, so it has more actual belt to pulley contact than the 8 rib setup on the P/C. On the front side of the jackshaft there is a toothed pulley that uses a Gates belt (like a chain) that goes to the blower. This setup is WAY more efficient, has much lower belt slip, is more adjustable as far as speed goes (you can change any of the three pulleys to change boost).

Beyond this - the ECS comes with a really good intercooler (it is a larger I/C than the upgraded P/C Stg II air to air), and comes with a real blow off valve that is capable of 1000hp standard.

So is it as cheap as the bottom basement ProCharger setup? No. However it is much cheaper than the ProCharger configuration you "should" buy.

$6400 gets you the ECS / Vortech kit, the Novi 1500SL blower, a good intercooler and a good BOV standard in a powdercoat or polished finish. You install the kit, and either find a local tuner to tune it for $500, or work with Doug at ECS (a forum member here) via email to tune it remotely.

With the P/C tune you have to send your ECU in to them, and it comes back in a week with a crappy tune.

Regardless what power level you are looking for, the ECS kit is a much better buy with a great amount of room to grow. It will out perform the P1SC setup at 7-9lbs of boost (and come on with more power in the mid range). You can add LT4 fueling and go to 10-12lbs of boost and make 700hp, of go to 14-15lbs and try and hit 850hp like I am.

As far as upgrades - you can get a Novi 2200SL blower (this is like the P/C F1X) which can do 1200hp all day long right from ECS for like another $700. But if you start with a 1500SL, you can get it upgraded to a 2200SL by changing the housing and impeller out to the 2200SL parts. And all the Novi head units can be upgraded to oil feed from self lubricating (that is what the SL means) to oil fed, and then you can spin them another 4000 - 5000 rpm and get another 3-4lbs of boost.

There is even a guy out there who offers a billet impeller for the Novi head units that will flow more air (15% more air out of a Novi 1500 - from 1450 to 1650cfm)

That is a great run down of these systems. I've always thought I would prefer the powerband of a centrifugal - more rpm, more power. Thanks.

I'm curious why zl1 guys get rid of their whipple for a procharger kit

only when trying to make more than 900 RWHP then they move to an F1A or like.

Not trolling...it took 3 attempts for you to just answer the question directly. Either way I don't think that time is bad at all for the lack of traction. With better DA and 60ft, it would of went well into the 10's and into the 130's so the combo is where it should be for the setup. Wasn't knocking at all...

The Newer PD's make power everywhere. For a street car the PD is more fun imo, at the track either can be just as potent with the correct setup.

ZL1 doesn't come with a Whipple. LT4 has a 1.74 TVS. And as of late I have seen 2 cars ditch F1A94's and switch to Maggie 2650 / Whipple's. It's all preference...again for a street car I prefer a power curve that feels like a big cubic inch NA motor opposed to something that doesn't feel any faster then stock until you get above 4k rpm. I have had both Centri and PD setups. 10-15yrs ago I would of said PD doesn't hold a candle to Centri, but PD has come a long way in efficiency...they make power everywhere and carry it well. Especially the 2650. It's comparable to a F1a94 on the top end.

I meant positive displacement type blower

Nice move, congrats. Very happy with mine.

I feel like the topic comes up everyday lately, so I’m going to preemptive-strike: DON’T RUN THE CANNED TUNE. Get HP Tuners and a custom tune with the tuner of your choice. Sorry... had to get that off my chest.

I think there is a misunderstanding here. Laynlo and King weren’t trolling, I think there was confusion between your combo last year vs this year and getting the trap speeds to correlate. I know I had to reread it all a couple of times to follow. But your centrifugal combo is stout, plenty of respect from me.

While Maggie gets a lot of love on this board (for good reason), so doesn’t Whipple, Eforce 2650, Procharger, etc. I have to say all of the Forced Induction board frequenters (is that a word? Lol) are generally very supportive of each other. We all make more power because of the great info that gets shared.

Haha yeah I’m having it custom tuned no worries!!!
