Supercharger / Turbocharger Results (INFO) Thread

[Darth_Emma]

I have an L99 with a CAI intake, Kooks 1 7/8" LT catted (and coated) headers, a Borla Touring exhaust, and a dynotune. I was a bit disappointed with the results on the dyno of 362 rwhp with these mods. The car is faster than stock (and sounds WAY better), but I want more. I thought the headers would give me more with the tune.

So, I'm looking at getting either a Maggie or a turbocharger. I am a bit leary of adding a cam because I've heard they are very tricky on an automatic.

I don't plan to race my car - except for perhaps a fun day at the track, but no serious racing. But, I do want the best and baddest street machine I can get. It is very important to me that my car be absolutely reliable and drivable on the street, but I want my car to be very quick. I really love driving my Camaro and I don't want to do anything to ruin that. - some folks have commented that a cam can sometimes harm drivability.

After reading this thread, it sounds like the Maggie is more what I' should be considering, but others have mentioned that a turbocharger might be better. I'm just doing my homework before I jump in.

Is it reasonable that I could get 500 rwhp by adding a Maggie to my L99?

The other advantage of a Maggie is I think they just look great. - I know, that's shallow, but a lot of the mods on my car have been cosmetic. I am looking into buying a hood with a plexiglass window on it to show off the engine. A chrome Maggie would look sweet!

Any comments as to what you folks would recommend for my car would be much appreciated. Thanks.

You will not have to replace the turbos - I am sure of it

We get $1100 foir an install or $1600 for install with custom tune on the camaro. However you can do the install yourself with relative ease

Nice, thanks for the information !!!! Looks like I will be going turbo speed then! Wish your shop was closer to Texas then in Cali.

Darth, you may also be interested in our HTV1900 supercharger fro Harrop. We currently have a FREE install special going on, check it out in the vendor sale section.

Considering LS3s are getting right near 500 RWHP on an otherwise totally stock car, with the OEM airbox too, I think you'd get there pretty easily, or dang near close, with a conservative tune. LS3 cars, with your similar mods', are averaging (from what I've noticed) from 510-530+ RWHP; add a CAI and you'll probably get past 500 to the tire pretty easily with a custom tune; I don't believe the canned Maggy tune accounts for full exhaust, like you have, and a CAI. I'm pretty sure you'd get to 500 pretty easily at about 6-7 psi.

Darth, that would look sweet sitting in your CGM!!

Side covers are sharp too!

500 with the Magnuson is a non issue even with the auto trans and I don't see why you would need a cam change. I agree the chrome Maggie smack in the center of the hood looks great. - We are happy to sell you a system as well

Likewise, you already know about our turbo system as well. 500 with the turbo is even easier - Here is an auto trans dyno sheet at low boost. Stock fuel pump with BAP

JR great insightful post

i am in toronto Canada area

in the past i have owned 2 87 grand nationals

so i like the turbo feel and sound

now i have a 2010 ss2 6 spd manual

i was leaning to a procharger system through the advise of a friend who works with them on many applications

i have a cousin who has an 80 vette 350ci stroked out to 383
heads done, cam

he installed an sts turbo system
8 lbs of boost he ran 10.91 with 1.72 short time on street tires

car squats hooks and goes

after reading all this i will look into turbo set up for mine

it is a daily driver...bone stock but is getting lowered 1inch with eibach springs and maybe an axle back borla s system just for extra growl

what do you recommend

gas is always 91 from shell but 94 from sunoco is also available

thanks

We have everything you need -







If you prefer I can jack up the numbers so it looks like you make tons more power than possible

And we have springs too




You will love the turbo. it is the way to go and worth every penny

[sandman69]

What's the opinion on the Hellion twin turbo or Supercharched big kit Kennebell?

[Granatelli]

The opinion was go with Granatelli Twin Turbo or the Maggie TVS2300 - or both

Just a few questions?

How does 5.5lbs of boost make 587hp and 597 ft/lbs? Assuming the stock engine made 370 rwhp - 5.5psi would produce 510hp at 100% efficiency - If you are quoting crank hp then 425 would turn into 586 - you must be quoting Eng hp not rear wheel.

7.5lbs would be 642 eng hp.

Your numbers make perfect sense and your video is a nice puff piece for Hellion. How do you tame down the compressor nice?

Can you really make 646hp with a 52lb injector? – What pump does that require?

So what are the other costs getting there? I know that you have to worry about heat and what not but...

The reference was to upgrades to the engine if you plan to go over 625 rwhp (750 crank). There is no heat to speak of with the new GMS/TTi system as the turbos are under the car and get a cooling effect as you go down the road. In fact, we are conducting a study right now that shows the stock cats at WOT for 10 seconds are already 90 degrees hotter then teh GMS/TTi turbo for the same time frame. The longer at WOT the better the turbos look.

The same can be said for long tubes with micro cats - they produce as much or more heat then the turbos do in that location. All of a sudden the turbos are look'n REAL good in a comparo to any of the systems out there

Sweet... I didnt think heat was an issue with the lower mount but... I was trying to think of non-monetary costs that it seemed you were referring to. I would love nothing more than to buy your system right now... But it is looking like I will have to wait to closer to the end of the year if I get a contract I am looking for. Thank you for your info. You have been a huge help on this topic.

I was wondering that myself...

[Granatelli]

Got a 2011 5.0 Mustang last night. We had beem working on the twin turbo kit for that as well. Customer wanted car back so I had to but my own. It is no personality like the Camaro. If fact there was a black 2010 Camaro in the parking lot like 20 feet from a black 2010 Mustang. Even in a sea of Mustangs, the 1 Camaro was best in class.

Driving it home, it seemed unstable by comparison to the Camaro as well. Lets see how the 4 cammer responds to boostage. I have a feeling lbs for lbs of boost the Mustang will react better based on the split cam profiles.

As to the question posed, if I did not explain properly, a hydrid roots blower or centrifugal or whatever supercharger might seem like less money to purchase but when you factor in you need to push long tubes, a CAI and quite possibly a cam then compound the labor to do all that and the Turbo System looks cost effective.

[IPSjeff]

Since this thread is stickied I will toss up our 6-speed TT results in here for reference:

663rwhp and 649 ft/lbs of torque on 8psi
581rwhp and 564 ft/lbs of torque on 5psi

Sweet! Thanks! I'll be updating as we move along.

[z28xtreme]

not trying to start anything with you granatelli as you are way more intelligent on turbos than I. what i do see a problem with was you were knocking ipsjeff on his kit for making something around 650 hp at 7psi not sure if it was SAE corrected or not. wouldn't your kit make something around 640 at 7 psi putting it within 2 percent of his kit?

i only bring this up because you were knocking the validity of his numbers. with the numbers you are showing here, you either were knocking jeff's kit for no reason or you decided to bump your hp numbers up just to compete? not sure which way it is.

i know as him being a vendor he wont say anything, but i just felt i had to say something.

i will be buying one of your guys kits...wont be for another year till i get out of germany though.

just keep up the good work and make me miss the states even more...

I was being sarcastic - sorry

We are letting our quality, fit and finish speak for itself. Our numbers are real world. But like it has been said, it is hard to compare differnet cars on different dynos on different days.

Half to STOCK dyno claims are already 30 or 40 hp higher than what we see from the dealer

[ipimpthisc]

whatevr company u chose , all these kits are great...its pretty much what suits u, and what power range and rpm model u like

[JAFOnomore]

based on the sheer numbers of magnuson blower guys here - it is hard to argue that it is not the best way to go. It looks cool too. I am having a GMS Cold Air installed and dyno'd shortly and I know that will also work with a mag blower if I ever get up the funds to go f/i

I love the stealth look of the turbo though. I think you could twin turbo your car and run the piping through the factory air box so it looks all stock
