I want to thank the Vette Doctors for tuning and installing one killler package on my CTS-V. The 821/846 dyno pull was with NOS. The car without NOS made 664HP/654TQ. The car has a head and cam package with a 10% overdrive crank pulley and a 2.55 blower pulley, headers, and a cold air intake.

Great numbers.

Any idea what the pulley mods and tune would have done without yanking apart the motor. Usually with boosted cars the cam changes add relatively few horsepower relative to very high cost - but don't get me wrong definitely more power.

This might have been done as much for aural enhancement as it was for power!! :lildevil:

Your V must be one of fastest V's on the road - maybe the fastest. Sweet ride, if you ever get any videos of it running please post them.

I'm also interested in how well your setup will hold up. I've ordered mods that'll take me to around 650 at the crank - a 100bhp boost is at my limit for feeling comfortable on the stock motor, and I'm not planning on running it hard.

Are you trying to get your V into the 9s? I'm looking for consistently low 11's with around a 120 trap.

are you planning to run it until it 'pops' or are you gonna upgrade the pistons, etc ? I know in the beginning w4m was shooting massive amounts of nitrous through his V and he beats on it constantly and the motor is holding togethor fine...So far i'm impressed with the lsa's & drivetrain durability and would hate to be proven otherwise.

I would love to go into the 9's with this car. But I will also be happy with mid to low 10's since this is my daily driver.

I don't want it to break but if it does then I will do a forged lower end. I am more concerned about the trans and rear at that power level.

Very good numbers!

With my nitrous kit i was only hitting 730~ hp average between all the runs. I never went higher due to thinking no one would want or need to go higher. I had no problems with my kit either. It was VERY happy on the juice.

Cam and heads make a large increase in power on this motor, and help keep the needed boost levels down.

Im sure the motor will last a while on your setup. IT isnt like you are on the juice 100% of the time.
As long as the fuel supply is good, and you are not maxed out on things, the motor should last quite some time.

Besides. Most short blocks forged with a large displacement are getting VERY cheap, so when it blows, just time to make it better. ;>

This is a very high risk build if the bottom end is not forged. The additional heat and pressure of that much boost requires forged pistons at a minimum, and I would add forged rods and main bearings and push rods in the process. The piston lands are the most at risk...if he starts to experience blow-by this is what is happening...

What kind of build have you done on the lsa/V ?

None. But I have years of experience with Viper Supercharged engines, the concept of using cast pistons in a Forced Induction environment is dicey at low levels of boost, but additional boost is just asking for trouble without doing bottom end work too.

I think the LS9 is the perfect example. With its additional boost one of the first considerations was the rods and pistons...and they remain one of the major differences between the LSA and LS9 builds...

Prof, That piston was damaged from too much timing or not enough fuel. It had nothing to do with being forged or not. It looks like a Dodge V10 piston. Possibly a truck one. Too much timing / bad tuning will cause that damage under the top ring like that. Also the Detenation you where getting was making the oil on the cly wall to thin causing wear on the skit.

To add, Yes a forged piston may handle more abuse to the knocking conditions, but it would still have been damaged eventually too from that same problem.

It is a piston from a Viper engine running 5.6 lbs of boost. It was tuned by one of the finest tuners of Viper engines available, Sean Roe, who also developed the supercharger that was providing the boost. Literally hundreds (not an exaggerated number) of us with Vipers have solved the problem by going to forged pistons and rods (Diamond and Oliver in my case).

The Gen III Viper OEM piston dome will not dissipate heat fast enough to prevent piston land issues in a forced induction environment. The timing advance in the engine is moderated by the use of water/meth and I am now at 10 lbs of boost on the same fuel pump and fuel rails...and the same tuner.

Detonation is a function of heat and too much air or too little fuel, so yes, detonation did occur...but if the piston had been forged it probably would have weathered the issue. Heat retention in alum engines is a critical factor and needs to be managed carefully, why else would the LS9 go to Titanium rods and pistons, certainly not for the tiny weight difference?

IMO if you are going to go much beyond 10 lbs of boost, it is fool hearty to not forge the rods and pistons in an LSA...but I have never stayed in a Holiday Inn Express...

...I would like to imagine that adding 5-11psi of boost to an na application like the v-10 would be riskier than adding a couple psi extra to an already fi engine.

09-09-09, 07:41 PM
Totally concur.

But the move into engine modification is filled with adventure, enter at your own risk...and have a ball in the process.

I had Carmen do a cam/nitrous package on my 08 Z06. The guy did an incredible job and made insane power.

I didn't think the LSA's would hold that much power without getting a fully built motor! Damn! Carmen thinks the V will handle it no problem?

Maybe we can meet up man or talk. I am really interested now...does the camshaft make the car shake a bit? My Z06 shook like an oldschool musclecar.

Also I'd like to restate that I have American Racing Headers on the car and that was one of the first mods I did to my car. That alone yielded 50 plus rear wheel horsepower, and I still have the stock mufflers. So if anybody is looking for some quick power just do the headers. I compared a couple different brands before choosing ARH. By far the best workmanship and quality I have seen.

Yes. Nick from American Racing Headers posts here somewhat frequently and they had a rather large thread discussing the gains they got from the installation of their headers.

While I'm not sure saying that everyone will get 50rwhp from simply changing headers alone (I don't think ARH got that much in the thread they posted!), I do agree that it seems like a very good mod for the '09 V

You wont get the chance if you break/throw a rod... and it cracks or goes through the block. Game over.
Rods are a must as they are powdered metal.

Hope a piston just lets go if anything, or lift the head.

Nitrous is amazing with force induction as the cooling (-90 n20) helps huge.

Get That thing to the track. I wanna see some mid to low 10's baby. Well:cloud9:would sure be nice too!

I would love to get a 9 second pass, but I'd also be very happy if the car ran 10.50's all day. Remember its a Cadillac! :)

if we could get into the 10's and run reliably i'd be happy with that:thumbsup:

do you have any idea what kind of boost you are running with your setup , what Fuel system upgrades you have ?
Thanks William

I think you should be fine, all the reading I've done on the pistons and connecting rods tell me they can handle it plus they even oil cool the underside of the pistons. I don't think the limitation of the V will be the motor at your power levels.... I think the limitation will be your tranny or something else in the drive train.

Dude, wake up. 800+hp on cast pistons won't last long.

They are hypereutectic pistons, if he's not detonating the pistons will be fine.

I hope you are correct...but I too have my doubts.

More to the point, if you are going to build this big why not forge the internals? It would be a very sensible precaution which would alleviate one of the major concerns.

Why not go with the LS9 pistons and rods?

Just an opinion...and you guys understand that opinions are like sphincter muscles...we all have them.

Some of what I've learned on this motor:

1) Sumped 9.1:1 Piston Cast hypereutectic coated skirt piston with sump in dome for compression control.
2) Swirl Wing Cylinder Head Cast aluminum cylinder head with wing in inlet port to induce combustion chamber swirl
3) Piston Squirter Block-mounted oil squirter for piston cooling
4) Connecting Rods: Forged Powder Metal

This tells me, al beit while not a completely forged motor, it can handle a lot, if timing is good and not detonating good power can be made with this motor. I still think the weak link is more drive train than motor..aka tranny... especially the Automatic.

LS9 - cast block, forged titanium rods (lighter for higher rev), forged pistons, heads are cast. So the difference is small IMHO. I think they went forged pistons was more for the higher rev than strength i.e. Titanium valves, less mass to move

I put a separate boost gauge in and it reads consistent 15lbs. But at high Rpm like over 4500 the boost falls off a bit to like 12-13 lbs. I think the supercharger looses efficiency being over driven this much. But on the NOS we have seen the boost levels spike around 18 lbs and then fall back to 15-16 lb range. I don't exactly know the specs on the fuel system upgrade that the Vette Doctors did, but you can call them at 631-841-0779 to get info.

Hey I think i asked this already but whose Pulley kit did you install? Is there any issues with the harmonic balancer . I am kind of worried about any excessive vibration wreaking havoc in the motor, as i would like to go with Jesse's 9.5 in crank pulley. Any one experience any problems with these mods?

I would be literally shocked if that's the case.

Very, very happy, but shocked... :p

I have Jesse"s 9.5 crank pulley with no issues at all.
