Should I say yes to the Blower?

[novanutcase]

Rodger and a friend were screwing around in the shop today and his friend had suggested to him that we should put a blower on the LS7. Rodger felt that it wouldn't fit but for $hiznit$ and giggles he had a Procharger laying around and decided to see what it would look like or if it would even fit.

It fit! DAMMIT! LOL!

What do you think?

What to do, what to do!!!:rolleyes::D

Adding a blower will add an additional 150 hp which would bring total HP to 650hp. For street that is a hell of a lot of HP to be responsible for! The car will be all over the place with that kind of torque and HP but DAMN it sure looks snug as a bug in a rug where it's at. It seems to have just made itself at home there! LOL!

i say no your car seems to be set up to be one hell of a road racer and the blower will not be good on the course. besides everybody has a power adder now a days, just put a nice set of heads and a cam and you'll have almost the same numbers and a nice soundtrack.

FINALLY!!! Someone to talk sense into me! LOL!

You are right in that a blower would not help me out on the track! Something to definitely consider! Thanks!

Well what are you gonna do when you run across a new ZR-1 or 08' Viper??? hehehe

Blower sounds good for those.

[69camarokid]

one other thing....

i read from Gm that the reason the Ls9 is a supercharged LS3 and not a supercharged LS7 is the the cylinder walls on the LS7 are to thin to run good sized amounts of boost without problems....

dont know how true that is, but u might want to look into that before u decide.

id say go ported heads, headers and a nice thumpy cam, that should easily put u over 600 HP

looks like a snail crawled up and found a home..

i say DONT do it.. hahaha

Hmm. I know I've seen that steering rack before. :)

[MrQuick]

quit being a pooss, do it do it....just kidding. It really depends if you are going to beat it or not. I think you will so NO!

Would that fit in your Stang?

[mpozzi]

Size will definitely matter ... for your wheels and tires to retain all that traction if you go this route. Sounds like fun but I also vote no for this adder for track use.

Cheers,
Mary Pozzi

[novanutcase]

Thanks for the knowledgable and insightful responses! In as much as it looks really cool and would definitely add HP I need to keep my focus on what the car is being built for and track use is definitely a high priority so I guess no blow!

What I find a little suspect, RODGER, is how the bracket bolted right on to the block. Especially since it was a blower he just "happened" to have lying around! LOL! J/K I know it's for another project he has going on!

Vince,

I'd so love to drop her in the 'stang but I don't think Procharger would want to sponsor me with the S/C only to see it end up in my 'stang and not the money shot!

I like nice blow jobs as much as boob jobs!

I would go for it..

More power is never a bad thing.

DO ITTTTTTTTTTTT:firefire:

[StRacerDuke]

Bad move! Leave it N/A for track use! Add a new cam & a tune to the motor and go run around with it. You can always add a blower later but I would suggest leaving it N/A for track use.

I agree.

If I understand the mechanics of the LS7, they flow really well and you don't gain much by a blower. Correct me if I'm wrong though. So if your not going to get that much gain, Why do it?

The blower would add just that much more density to the air already flowing into the motor. The problem that I see is more in the block itself since the cylinder walls are fairly thin and adding a blower would add stress that the motor may not be able to take in its present design. The new LS9 has been speculated to be either a blown LS7 or a blown LS3. Consensus feels that it is probably the LS3 because of the issues that I mentioned above. Have they blown LS7's? Sure, but you have to be very careful about detonation in the motor when your tuning it. I would need to find a shop that has a lot of experience in tuning LS7's since most dyno shops are setup and have most of their experience tuning 350's. 58x reluctor, finding correct TDC these are just some of the issues that would need to be sorted out and dealt with and if the shop is not experienced enough it could lead to disasterous effects! Not to say it can't be done but is it worth the time, trouble, expense and chance that something could go wrong?!?

How about a nice solid roller cam? Contact me if your interested. I have a guy who has some proprietary grinds that have already proven themselves in off road racing. I'm picking up the rest of his line of stuff for the shop cause I like the that much.

If not please don't do a blower. It's too easy for such a well built and purposely modified car. It seems like an after thought to just bolt it on and say looky here. Besides solid rollers sound better

[Gordz32]

No go on the blower. Heads, and a nasty cam will suit just fine on this car. How heavy is the car?

[powerjames]

ProCharger actually makes a LS7 Supercharger system for the Z06 Corvette. I'm sure you could follow their guidelines and tune up and be pretty safe.

150 shot of nitrous ought to do the trick! :naughty:

OH SURE!!! Just add more gasoline to the fire!!!!

Hahahaha!!! Thanks for the link James! Good to know that it has been developed by a reputable company!

I was gonna say! Nice save James! LOL well now that opens a new can. I say do it now.

A friend of mine is having an LS7 built and tuned by wheel to wheel in Detroit. You might try them. Also Jeff Schwartz does alot of these motors, maybe he would chime in or give him a call.

[LowBuckX]

Dont do it... To much can be just as bad as not enough....

If you cant put it to the ground its wasted.

[andrewb70]

My vote is to keep it NA.

i dont get why a blower would make it worse for the track???

Also, GM have to build their engines not to fail for 100k miles in any conditions with any flaws or weaknesses in the castings.

I would think you could have much more than 150bhp increase before you start stressing a big V8 block. lol

You can get 7-800 bhp out of a 2 litre 4 banger without smashing blocks....jeez.

When we say track we mean Road Course in case you were thinking drag strip. For drag this would be a no brainer but the car it's going on is being built as a street/road racer so some of the concerns have been the durability of the block and exiting the apex of the turn in which the blower would introduce a large jump in HP which might introduce tire spin. I would have to be VERY careful about feathering the accel as I come out of the turn. If you've road raced you understand just how hard that is to do among all the other things that you need to be keeping track of on the course.

Actually if you were to use any kind of power adder for a road race car, a Pro charger wouldn't be that bad. Since the supercharger is belt driven, the boost curve is very linear. If you ever look at a before and after dyno sheet on a procharger car you will see that there isn't a big torque spike down low. As RPM builds, so does boost, so does power. The the torque curve tends to have a similar profile to the NA combination except its just higher.

I keep drooling for a ProCharger and you have one in your car and you are going to let it back out:seizure:

If you can afford it :twothumbs
