Cadillac CTS-V - 600+hp on 2007 CTS-v

looking for 600+ hp. has to be very reliable on street and smoggable. i was thinking a magnacharger, headers from a SC CTS-V (since they should be in junkyards now), and a cam. still want decent gas mileage. let me know my options, even heads/cam if i dont need supercharger.

you wont reach 600+ with a heads/cam package

best option is to put ls3 heads on ur current motor and go towards the eforce

If money isn't an issue then procharge it and bore n stroke it

dont want to stroke it. trying without heads too. so cam/supercharger/headers wont do it?

i dyno'd 330rwhp

A 112 Maggie will barely get you into the 500's, if that. If you want 600 whp from an 07 V you will need a stroker with a Pro-Charger (lots of time and even more $$$), or a shit ton of spray. A modded LS7 would also get you there. Bottom line, you are looking at $10-$20k depending if you know how to do the work yourself with the engine work and REQUIRED SUPPORTING MODS. Honestly, spray would be the cheapest route.

If you cannot do the work yourself, add to that.

If you want 600+ whp...sell the 07 and get a V2, it will probably cost less in the long run.

Unless you do all of the work yourself and your time is worthless.

Without heads your stock compression ratio of 10.9:1 is too high for the amount of boost you will need unless you want to run race gas.

if the OP is meaning 600hp engine which would be a rough guess of 486rwhp.
Roots type blower is your best bet, or n2o.


if the Op means 600rwhp meaning 740 engine.
lol, basically everything needs to be changed or upgraded. Fuel system, pump(s) wiring, basket, rear end, clutch, engine mounts, headers, heads, cam, blower, block forged, tune, SD capable sensor changes, on and on and on..... we are talking thousands and thousands of dollars. Believe people when they say.. a V2 is a cheaper route in the end.

E85 (big fuel upgrades required) is an option for the stock compression for boost setup, but the stock rod bolts/rods / ring lands will hate you, and tell you very quickly.

The limit on the LS2 setup (using a procharger) is roughly 550rwhp... give or take 10 for reliability. (you better have a good tuner)
600 is possible however, but you are beyond what I call, reliable, as you will need to be around 12 psi of boost, with supporting mods. Running Meth Injection would be mandatory.
Its how long can those stock pistons, rod bolts hold out...

I think the better question should be, why do you want that specific number? It's somewhat of an intangible figure.

Wouldn't you rather your car "do" something for you?

Most mods on these cars have more to do with getting the power to the ground rather than increasing the engine's output. 600 hp would break this stock rear end in half within a day of "playing" around. A solid alternative to our GM given glass differential is going to run you around 4-5g's if you can't fabricate one yourself.

As mentioned before, the cost of the v2 is starting to seem more and more practical for your performance desires.

AMEN to all of that.

600rwhp in a V1 will not be reliable unless you build every part of the driveline. At that price you could be damn close to buying a V2 with cash.

Call the Team America World Police. They may be some help.

.......

I want to be able to beat the new V's and M BMWs

You don't need 600 rwhp to do that.

so what do i need? magnacharger, cam, and headers? that enough? powerwise?

Those mods will put you up there with them.

what do i need more? heads?

good heads, cam, intake, and exhaust would getcha pretty close.

Close to beating them or close to 600?

Magnacharger cam and headers will make you faster than a stock v2. You only need about 475rwhp to be faster due to your weight advantage

What cam is good with charger? Which wads should I go with If I decide to

id research and see if the E Force they have for the ls2 corvettes would work... the 06 07s have stronger rear ends than the 04 05... im planning on turboing my 06 here in the next few months... right now its a heads tiny cam (219/230 .605 .604 117) pushing 448 418 on with a tune off the MAP sensor... if you can stick a Eforce 2300 should do nicely

Ls9 cam is a good one.

How's the thunderracing supercharger cam or the new comp lsr cams?

save all your money and buy a new lsa motor with some blower porting and pulley changes and some bolt ons they make mid 600s

i would just sell the v1 and get a v2 and slowly mod it its going to be faster right out of the gate i thought the o7s where the first gen v2s?

Got a good deal on it. And only 20xxx miles

im looking for the best setup without taking out the engine. thats why i was looking at charger, cam, and headers, and heads if need be.

what would be the power difference between the ls9 cam, thunderracing charger cam, and the two Comp LSR cams?

BUILT REAR, heads, cam, intake, exhaust, nitrous and tune.

Thunder Racing does not recommend their Blower Cam for use with a Maggie 112...they will point you to the CheaTR V.3. You have to really decide what you want...the Maggie is an under curve supercharger and if you choose a higher LSA cam (stock cam is 117*, CheaTR V3 is also 117*, LS9 is 122*) you run the risk of running out of blower with the little 112 where these cams really start to wake up in the upper RPM range.

If you can do your own fabrication work, an E-Force can be had for as much as the 112...and you will have a lot more options for everything else.

[FONT="Century Gothic"]If beating the new v and m5 maybe weight saving would be a more productive and cost effective way to go. Or shoehorn the new motor in your car... or both.

so how much power will i be looking at with the cheater or LS9 cam, maggie , and headers. how much more with heads?

im not selling the car

Just get your ls2 stroked to a 402, throw a donkey dick cam in, and a set of good heads. Maybe even a fast 102 intake. Then you'll make more power than a v2, and have a shit load more durability than a blower on a stock bottom end ls2.

Im at 490 with a ls9 cam, Maggie, over driven balancer, headers etc. but my motor is forged and I dropped the compression to 9.8/1 which prolly hurt my numbers but I plan on NOS too so I built it for both boost and juice

i'm not a fan of how high the lsa is on the ls9 cam. 122.5... sheesh.

I hear that but it makes the idle and drivability butter smooth

So Chester v3 cam and Maggie should be around 550?

So Chester v3 cam and Maggie should be around 550?

No, you would need a pretty big cam, really good heads.. Over drive the hell out of the Maggie and get a spot on tune just to get over 500

Oh... K well the comp cams work better with Maggie then? Would like it powerful, but not shaking the car like a aggressive cam. And smoggable

SSRZ28, to put it into perspective, I just bought a 408 stroker, texas giant donkey dick cam, fast 102 intake manifold, and have prt stage 2.5 heads, and i sincerely doubt i'll be breaking 550.

Ok thanks. Well I dyno'd 330rwhp. I think I'll just do the cam, maaggie, and headers. Maybe heads too.

Any recommendation on cam that will sound nice, have good power, and smog.

And a recommendation for which head and cam with Maggie.

Are the stock headers off a sc ctsv good enough?

How much power is the 07 rear capable of handling?

PISNUOFF puts over 500 rwhp through his 07 rear. as long as you don't violently hop, you will likely not break your rear end.

I don't have any experience in all this but.... I was thinking LS3 heads not milled thick head gasket, an e-force and a cam. I have no idea if it would work well but in my pretend world it runs great. :)

I have done it and its not that easy. The cool thing about the eforce is you can use LS2 heads.

If your going to put LS3 heads on then you can consider a G8 maggie kit as an alternative

If you keep asking what heads/cam etc would be best you are going to get a 100 different answers. You would really be better off working with a vendor directly to help you focus on a direction to go. If you have to stay within smog requirements, you will need to stay at least -7* overlap, which is viable and will work well, but must be properly matched with all other components. This is the difference in a carefully planned "build" and having a bunch of random ass parts thrown together.

I'm a 418 LS3 with a medium cam and GM Performance ported heads with long tubes. I made 510 through a 9" rear end. I assume the 9" eats 10-15 rwhp.

That's with a FAST102 as well. Sry

I've decided to just go with exhaust and Maggie. I want to keep it street legal. Are their any legal headers (shorties) that will have a significant gain over the manifolds off a SC CTSV

No. Shorty headers are a waste of money anyhow as LS manifolds flow fairly well (the OE cats are more of the restriction). Get 1 7/8" LT headers from OBX or Kooks and make sure you wrap the primaries when you do. Also, make sure you change the motor mounts when you put the headers in. Depending on the dyno, you should be in the 430 - 480 whp range when completed.

Well then should I just use my factory manifolds or the ones from a SC ctsv? Or are they the same?

Are you talking about V2 manifolds? I don't think you can use them...

Which ever ctsv came supercharged

Those are meant to fit a different engine bay and exhaust setup. Likely not transferable, and you wouldn't likely see any gains either.

Almost depressing enough to want to sell the V and go back to an fbody.

Well then should I just use my factory manifolds or the ones from a SC ctsv? Or are they the same?

They are essentially the same part with a few very minor changes. As I said, the OE manifolds are not too terrible..it is the cats that really impede flow. Removing the OE cats usually gain about 15 whp on a N/A setup, so you might see a little bit more on a F/I motor. Headers will get you another 10-25 whp with F/I (again, depending on the dyno) and will help torque everywhere.

Don't want long tubes since they are not smog legal. So I'll just keep the stock manifolds and get high flow cats with a Maggie.

you can run long tubes with highflow cats and itll be smog legal. kooks makes the long tubes with catted connectors.. they prolly have the best cats of all the companys too

He's in Cali...

Moving the cats makes it illegal

u cant have headers in cali even with cats???? thats pretty gay if true

Moving the cats makes it illegal

thats rediculous!!! how would they even know where the stock cats mount, they are mounted all over the place in various cars. that blows

Socialist Republic of California. Ideologists only pin you down and make you slaves to their own moral compass.

yes, but some smog shops will still pass you... it just depends on how knowledgeable or much the guy really cares.

There actually aren't any smog legal high flow cats for the V1 either. But there is really no way for them to check when they smog the car. My RT cats are just a little smaller (actually a lot) than the stock ones, but they are in the same location so they don't notice.

Some members here have gotten away with it. There are also some zip codes here in CA that are exempt from smog. If you register the car in one of those areas, they never send you another registration with a smog requirement.

You know which zip codes those are? i think it's about time i get a PO box somewhere...

Is it possible to establish a residence in another state or something with a relative? When I lived in California I was a Montana resident which negated all of these concerns. Best of both worlds.
