Supercharger vs. Turbo - Which is best for Torque?

[austinite]

Problem I am running into is most of these mods only perform well at higher RPM's. I'm looking to get off the line a million times faster and get to 100mph in no time. I'm not looking to take off from 80mph.

I have a 6.2L L94 Engine (GM obviously). 403HP

Cam, long tubes, dual exhaust, Intake, No cats. Level 2 tune.

Last Dyno was at 481 HP.

I haven't changed out the gears yet and I know that will make a difference, but it's an ALL WHEEL DRIVE and it's just so hard to justify the price.

Any pointers here?

Super charger..... Roots blower. The power is always there. Turbos hafta spool up....

How's ur compression?

[Hazard]

Looks like you're lookin at $6k for a blower kit

[austinite]

I don't know for sure. Factory is 11.5. Likely close or the same.

Same kit Lingenfelter used.....

No cats? Jesus its a 10k fine here for that��
Its all relative and comes down to a dollar price and personal preference. $$$$ Superchargers have a nice whine noise. Forced induction is sik but NA is awesome. a nice big cam and a stroker kit is pure boss. If you have the cash Just get both.

Yeah I've seen their trucks. Man they're mean.

Yeah that's about what I expected. Gears would be around 5k. But a blower will make much more difference.

[Hazard]

Seems like Hennessy has an awesome kit to bring you to 600hp. You'd just have to have them eliminate the exhaust since you have one.

I bet it costs an arm and a leg though. 10-12k I'd assume..... Hennessy is expensive but they're one hell of a badge on your vehicle!

Yeah, they're only a few hours away from me. And yes, you hit the nail on the head... 12k is what they asked for. They do great work but I can get to 600HP for about 7k.

That's why you take your stock cats and gut them. No way to tell unless they take it off and look inside. Ive gutted or replaced the cats on 3 different vehicles and each one passed emissions better without them and No they did not have high millage.

Agreed, blower over turbos for low end torque and of course gearing.

Depends on the turbo you want you could use a smallish turbo and run medium boost esp with the volumetic efficency of the v8 engine you have you wouldn't have to go wild to break the 600bhp mark.

You could go for a rotrex supercharger which is basically the inlet side of a normal turbo which will hit plenty of boost and there is plenty of kits for your car. You may need to run bigger injectors and fuel pump with your high comp. 11.5 is high enough but modern turbos run that comp but they have knock and map sensors running all the time to pull the boost back if needed.

Wow. Never heard of rotrex. Reading up on it. Seems to be the real deal and it's less than have the price of what Ive seen for supercharges. Thanks for the heads up.

No hassle. You are near Dallas aint yeh? Try going to 21st century cars in Dallas we randomly visited there when I was in tx 2 years ago and they had a twin turbo camaro in there with a zo6 c5 twin turbo too and a modded ctsv also.

Yeah and all that gets to be a big PITA and $$$ quickly. Ive been lucky compared to many I have read about. I went from stock 9b twin turbos and 360 injectors too 13g twin tubos, boost controller, 550 injectors, high flow fuel pump, air fuel controller, ping sensor and about $200 every time you want/need to run it on a dyno for tuning.

Lmao

I have a Honda accord 4cyl and the baby car seat adds about 25hp. The 2nd car seat will put another 25hp but ill need a dyno tune

Unfortunetly as you know lb bhp comes at a price especially when you have done the na mods already there is very little head room left in the engine.

Any form of forced induction will cause the car to need extra fuel etc. And changing the injectors isn't too hard but the ecu that may be needed isn't cheap but certain standard ecus you can flash etc and use them.

pretty sure it is an Escalade

x2. You'd want to go with a roots type blower for instant power. Centrifugal Blowers can put out higher HP & TQ numbers, but you wont get the power until around 3000 RPM & up. Kenne Bell and Whipple are two good brands. The KB will have higher blower whine which is cooler IMO. Once installed, it's all in the tune. You need a very qualified shop that will both install & tune it on a dyno for you. The shop must get the air & fuel ratio set correctly which only a qualified tuner can do. Once tuned, I'd recommend you have it re-tuned on a dyno at least once a year as the tune they put in can fall out of specification and possibly grenade the engine if not maintained.

Dont be so concerned with the final HP & TQ numbers and spending a few extra grand. Sure, anyone can have 600 hp at the rear wheels, but only a good tuner can make your chosen set-up run well in all driving conditions (i.e. at idle & throughout the RPM band). If the tune is crap, you'll be very disappointed with how the car drives. What good is saving 3-5K if the car runs poorly after the install...

Agreed with all you said there man

[bsh]

Put the biggest ProCharger u can fit...

[wicked442]

Must have gears to match the rest of the set up. Run a 2 step limiter with your turbo. Good gas mileage with a turbo over a roots style blower and bring your power in when you need it with the limiter so you can spool it up on the line.

[austinite]

Semi Daily. I drive it the day I want to take it to the track. Lately it's been a few times a week.

pretty sure it is an Escalade

Correct.

Interesting. Thanks API, I def. don't want to sacrifice anything at lower RPM.

I know that's true. I already shelled out a fortune for everything else, I might as well do it right. Thanks again.

Yes, gears are def. a must. But I think I'll wait until I get the hang of the blower. If I get it all at once I'll want something else, lol.

Whatever u do turbo / blower type! Remember the combo is cam convertor and gear... The set up is the set up motor wise however u make the power the idea is to be able to utilize that power in the most proficient way... I.e. Great performance... There are many great builders/tuners out there and I personally know a few if u would like I'll give u some contacts! Just pm me

Thanks man. As far as tuning, I believe I am working with one of the best in the world. (I'm sure many feel that way).

[bsh]

Okay cool... I've drag raced for many years and had meant build under my belt! My last is in my av it's was 1050whp (@all4 wheels, lol) and a daily driver! It on E85, if it's available I recommend it, more boost less inlet air temps and cheep as shit... Use a lot but it's worth the boost, haha

That car ran 9.1 @159mph and I drive it to the track and back with the a/c blasting and the radio cranking

[bsh]

FYI- turbocharger technology has come a long way in just a few years! Boost controllers, etc.. Turbo selection is crucial of course and any tuner worth their weight can do a selection... Having all the power in the world is useless unless u can apply it in the range ur intending it's use is for... In a case like what u have mentioned a small TT setup might be worth considering, just my 2cent

100% because most people do not drive full throttle. Drivability is the biggest and hardest thing to accomplish. Most who are only worried about HP and not drivability (reliability) the engine typically doesn't last long. It would suck to drop $10K into an engine and have it blow up within 2 years.

Thats why they are called dyno queens. All the power in the world is useless if you can not get it to the wheels

my point exactly... Power performance reliably l will Take over rawpower #'s any day... In the end u want a daily that kickass and causes u no problems ! It can be done Tuners are all about getting big #'s to brag about in their builds.

I owned an 03 ford lightning with a factory roots blower, added a chip some power pulleys, long tube headers and a few other tricks and that thing screamed and hit 142mph. So I'm with Hazard.
