Respect you guys are still tuning 3800's, Wish GM still had those available in modern cars, Miss my 40th anniversary GTP. Thing ripped with the zzp tune
I recently just had to drive my pacecar and the power wasnt what i remebered after feeling a tuned lnf. Great platforms to work on tho compared to most.
@@ianscheurer that was pretty much the weak point with that platform. I cant believe they still used the same transmission in the LS4 cars as well. Pair it up with a nice 6 speed or a stronger auto trans.
if I upgrade the rods, pistons, piston rings, rocker arms, pushrods, valves, and headstuds, would a 270k+ mile 1998 grand prix Daytona pace car with the 3800 supercharger, would the block be able to handle the power? and ofcourse replace all gaskets too
Why would you need to upgrade any of that? These engines have ran deep into the 8's in the 1/4 mile with 100% stock bottom end. They're strong as hell.
You weren't "Out of Blower", you were "Out of Intake". A Common misconception about Roots. All you're doing is just increasing the pressure of the same volume(Mass) of air. The more air you can get INTO the blower the more power you will make. You can crank the PSI all day long but if you don't get more air mass in to it, you're not doing a damn thing. There's a reason why Weiand blower guys use a big ass throttle opening on top fuel cars.
Just picked up a 1998 GTP, high mileage but in good condition, for $1,200. I own cars that are a lot quicker but the GTP is really fun to drive. Just installed the fenderwell intake from you guys. I'll be doing more shopping soon
Ryan just released a video that talked about the Eaton M90 efficiency range being 7-9lbs of boost, yet these guys are pushing it up past 12lbs? I don't understand, could ZZP explain?
The science behind it is above that range the blower generates more heat so you get diminishing returns. This is negated on an intercooled car as the intercooler can remove in excess of 100 degrees of intake air temp.
@@joeyf8368 Bingo. There's a reason they got the nickname "heatons." Much like some tunes pushing the 1.4 turbos to over 20 pounds of boost on a stock cruze/sonic, you're so far outside the efficiency range that the temps are getting stupid high.
Based on scans, nothing. Although, like mentioned in my comment above we'll be doing a proper A/B test on Zoomer's car here soon. This video was more meant to showcase the sound of the equalizer. It sounds great in video but even better in person
@JPL Performance Honestly, not enough to worry about. 3" is overkill for 99.9% of cars. We didn't have to jump up to a 3.5" downpipe on our 2.0 LSJ that made 898whp until about 600whp. Zoom's car runs a 2.5" catback that necks down to 2.25" after the rear axle. My turbo Ion Redline made 408whp on a 100% fully stock catback a few years ago. Exhaust size doesn't matter as much as people make it seem.
@@gbrunner24 exactly. People put a 3 in exhaust on a stock Honda Civic and think they're making it fast when really all they're doing is making it sound like shit.
So Ryan d says don't pulley up if your mods dont support it, but this video says otherwise. My concern is that this video is just trying to get me to spend my money. Im interested were this goes. Like zzp for filling the gaps in the performance market.
We understand the confusion. Fortunately the mods on this 3800 allow us to run a smaller pulley. It has a full-stack intercooler, bolt-ons, E85, and an XP Camshaft. As Ryan said, you want to match the proper pulley to your build and for this build we needed a 2.6 to achieve the desired boost.
I'd add in a little meth on top of that intercooler and bump the timing up a tad 🤘. You said that's the party pulley. Let's party brother lol. Love it man. That's my favorite color grand prix too 👌. That exhaust note is an absolute WIN. even if there where no gains to be had. That alone is worth it after years of sounding like chain saws, you guys finally made something for us to sound clean. Well done 🤘
Teat this product on a bone stock m90 setup. Not a xp with major overlap- a xp cam is not a simple setup for most. Nor does it give us any info what a 3800 can do. Show us stock #upgrades because with that setup u should be better than 310hp
This car has been through multiple revisions of prototype equalizers over the past 8 months. The equalizer took a bit more time to develop than we thought, but we'll put together a great A/B test on Zoomer's car here in the near future 😉
My Guess Was 325WHP After Hearing Mods! It Would Have Made It If The Blower Could Push Out 12lbs hahaha. That Equalizer Pipe Has Me Curious On How It Sounds In Person. I Like The Stock 3800 Sound. This Probably Makes It Sound Like An Import. I Miss My Turbo Monte Carlo. Thing Was Making 480WHP With 210,000 Miles, Cam, ZZP Front And Rear Logs, 80# Injectors, Water Meth, Blocked Off M90 And On A Unstable Fuel System. The Unstable Fuel System Finally Caught Up To Me And Melted 2 Pistons Top Of 3rd Gear At 150MPH LMAO. (Don't Use The Stock Fuel Pressure Regualtor Above 300WHP lol) She's Been Down 9 Months 😢. Short Block Is Ready But Still Been Waiting On My Cylinder Heads To Be CNC Ported In Indiana. Also Milzy Is Making The Turbo Hot Side. The ZZP Logs Keep Cracking On Me Like Crazy (They Crack Around All The Welds On The Flanges) And That Stupid Donut Gasket Never Seals If Dealing With Turbos And The Added Back Pressure Between Heads And Turbo. The ZZP Logs Will Not Give You Issues Unless Your Turboed.
I have to say this is NOT (I repeat NOT) a “basic build”. Anything with a cam/intercooler/springs/e85/2.8 pulley,,,, I’d say is on the verge of a highly modded engine. Since the 90’s everyone I’ve known considers a mild build is intake/header/exhaust/tune/ slightly smaller pulley. And what I don’t get is it seems like people contradict each other. I thought “you never should rub anything smaller than a 3.4”. This is coming from “other people” there. It’s like no one agrees. I do LOVE your build and I have the parts for a “mild” build, but am waiting for exhaust and power logs or headers.
Yeah there's a little confusion but let me try to clarify some things. 1. Trying to run a too small of pulley kills power because the supercharger gets out of its efficiency range. Anytime a supercharger or turbo gets out of its efficiency range, it starts blowing extremely hot air. Hot air means a big PSI number, but in reality it's just hot air. Think of 90 PSI in a semi truck tire vs 90 PSI in a bicycle tire. Now technically they're both read "90 PSI" on a gauge, but the volume of air in the two is tremendously different. Beyond that, hot air is less dense than cooler air. Less dense = less oxygen, less oxygen = less power. 2. Hot air = detonation. Superheated air will easily combust, which is bad because the air/fuel mixture will combust before it should in the cylinder. This is called detonation, or spark knock. Luckily, GM engineers knew this would happen so they have what's called a "knock sensor". This is a little sensor that detects spark knock and tells the ECU to pull timing. The problem is when the ECU pulls timing, it pulls horsepower. So now all that horsepower you just spent a lot of money on for that under size pulley, the ECU just pulled out of your engine! See, less timing = less power. Less power = less heat and less heat = less detonation. So now you understand why it's not good to "crank up the boost" so to speak, but why is this car getting away with it? Couple reasons. First this car is running e85. E85 has the octane equivalent of about 103-105. This significantly decreases the chance of detonation. 2nd, this car is running an intercooler. The intercooler can lower intake temperature by over 100°F which furthermore reduced chance of detonation. Finally this car is fully modded to take advantage of the boost including but not limited to: a low restrictive exhaust, cold air intake, 180° thermostat, cooler spark plugs, and safe tuning.
Smaller pulley is not always the best answer. It's all about finding the best pulley for the efficiency range of the blower and your setup. Typically going too small on the pulley size will bump the HP a few but give you some more torque. With that though comes more heat. This is why I'm sticking to a stock pulley on my LSJ build. Less heat, more reliable power and I can run a ton more timing out the top end.
