Guess my max hp and torque with this setup
Here are my power mods:
Engine:
- 03 Cobra block
- Stock iron crank
- Forged rods
- Manley 0cc pistons (flat top)
- 11.5:1 compression (fly cut)
- Comp XE270AH stage 2 cams
- Comp upgraded valve springs
- Stage 3 ported PI heads by MMR
- Canton windage tray
- Underdrive pullies
- some if these aren't power mods, but I listed them anyway -
Intake:
- eBay special cold air (ie. some generic metal piping and a cone filter)
- Stock MAF meter
- 75mm BBK throttle body
- C&L plenum
- Stock PI intake manifold
Exhaust:
- MAC long tubes
- Prochamber
- Stock cat back tubing with flowmaster 40 series
Computer:
- SCT custom chip tuned
Fuel:
- Stock fuel system
- 91 octane fuel (best I can get at the pump in CA)
What do you all think my horsepower and torque should be?
I did not list suspension or tranny stuff because I'm just interested in what this setup should produce at the wheels.
I do have all of these mods in and I want to see if my power is close to what it should be, mainly becuase I'm considering installing bigger injectors (30#) becuase I think I'm maxing out the duty cycle.
Any suggestions what to do next, go right ahead. FI is out because of the compression and nitrous is still a maybe. Yes, I have gears.

Sounds like your all set for nitrous to me. Why did you go 11.5:1 compression on a forged cobra block though? You can still run low boost on a s/c or run nitrious which is what I would do.

With those mods you need a dyno tune anyways so no need for a guessing game. If anyone could come within 20HP they could be like the guy at the state fairs guessing weights and ages and such! Just kidding man. 11.5:1 and 91 octane, did you have alky injection listed because you are going to have to back the timing quite a bit for that combo without an additive and since you mentioned 91 I assume this is not a race car or do you have plans for race fuel at the track? Who did the tune for the SCT?
How about a WIDEBAND o2 METER?
Just curious but since you dropped a few bucks with that motor why not go with a KB SC? They are 50 state aren't they? Sorry for all of the ?? but that's what that assembly brought out! Good Luck, mark

Hindsight is always 20/20. I should have gone low compression with the KB. I would if I were to do it all over again. The compression is too high and I detonation issues. I screwed myself choosing the compression because I can't go FI. It's a street car, but not a daily driver. So Cal tuning did the tune and they did have to yank out a bunch of timing. But I have a theory that they had to yank timing because of maxing out the injectors, but they said the A/F was all good throughout. How about this: should I be over or under 300 RWHP?

ORIGINAL: TorchRed04GTSo you had PTV problems with the comp 270's? I was thinking about these on a stock motor.
For the thread starter I am going to PM you. mark

well we have basicly the same setup except I am changing mine for now. your horspower and tourque will probably not be anymore than mine. but it maybe. you should upgrade your fuel system I did and it helped. I am changing my compression from 10.5 to 9.7 then straping a kb blower on so thats enough about me though I would say you would exceed 375 hp and they flywheel abd about 400 tourque at the flywheel!! thats is if tuned properly and having the nesecary fuel upgrades
