i have a 01 blackbird im slapping on a set of hooker LT's and O/R ypipe what will be the rwhp gains im pretty sure my car is already doing 350rwhp as of right now i race a 05 gto m6 and i walkd the **** out of that thing.. the headers and ypipe is c.c

 

25 or so RWHP.

 

stock 350 rwhp? ....

 

lol at 350 rwhp with lid and catback

 

it's what dreams are made of

 

if u guys read his sig it says stage 2 gmmg......350 rwhp is not totally out of the question.

 

man i you guys all drive f-bodys and never knew the true stats on the phase 1 blackbirds the reason i know im putting down 350rwhp is because i race an .. 05 gto m6 and hes putting down like 340 some and i pulld him bye 2 cars.. and no its not just an air lid and catback. air lid mas air tb 373's dyno tune shorty headers catback 160 ts short shifter and ls6 intake.. has to be 350rwhp i race a 02 c5 m6 that was doing 356rwhp and me and him coud not brake loose from each other bte it was

 

sorry a bout the miss speld ^^^^

 

not trying to dis you, but there's far far far, did I say far, more to it than that.

For 1 the GTO if it's an 05 has 400bhp. But it wieghs a fair bit more, so 400bhp in an Fbody should mean you'd win. BUT driver has a great deal to do with it, how do you know the GTO was being driven to it's MAXIMUM potential??

Also have you ever heard of the term deminishing returns?

Basically you can only do 2 things in terms of bolt ons to increase BHP.

Remove items that ACTUALLY require HP such as air con, alternator, water pump. No matter the state of tune or amount of HP you are making you will see similar gains by removing them.

However, induction and exhaust bolt ons can only free up so much power before the internals of the engine become the restriction. There more mods you do the less effect the others will have as for each mod you will be closer to optimising the performance. For prove of this, there are not many stock internal non power adder LS1's that produce more than ~360rwhp and that's probably on a dynojet so it's also a high reading.

If you assume 300rwhp as a realistic stock number
LS6 intake - 20rwhp
LT's - 25rwhp
Catback - 5rwhp
!CATS - 10rwhp
Ported TB - 8rwhp
Lid - 10rwhp
K&N - 2rwhp

If you believe the numbers literally even those simple mods should give you 380rwhp - THIS IS TOTAL BOLLOX

The numbers for each mod are probably correct if that mod was applied to a STOCK car each time. If you already have mods then each gain will be less.

In all reality I doubt very much that there are any STOCK INTERNAL non power adder LS1 producing much more than 400bhp at the engine. which would put an Fbody at about ~350-360rwhp TOPS.

Miss-calculated and optpmistic claims of HP do NOT actiully make acar faster or more powerful.

 

well i never said 380rwhp.. i said 340rwhp 350rwhp at the most

 

What he fail's to mention is my car had a stock shifter which ton's of gto' owner's complain about, and at the high mph roll's it was head to head if you want to try it again bring your car to tn im a 100% sure you will get smoked' Ill bring my camcorder you bring your wallet ..

 

what the hell did he just say?

btw, to the guy that started this thread, post up some pics of that Blackbird! thats not something you see everyday, at least not where I am from.

 

- I agree with 300bhp/ton, F-body's have got to max out around the 360's from bolt-ons and each gain from a mod is ralative to what mods the car has already. 350 RWHP is a very rough gusstimate after racing a GTO with there being so many differences. My guess after the headers you'll have about 360rwhp, get it dynoed, let us know. Also what is a Blackbird?? As far I know I thought there was Firebirds V6's, Trans Ams V8, Ram Airs V8 and Firehawks V8, is this some sort of special version

 

you are probably at 330 max.. i know you would like to think that you are making more power, i understand, and I'm sure your car is fast..... but what you beat on the street has nothing to do with power.... so don't go talking about how much power your car has until you dyno it

 

FWIW:
02' Camaro SS with SLP LT w/ random tech cats, SLP center mount exh., ASP crank pulley, blackwing lid, Granatelli MAF '85 /no screen, bellows, HP air-filter and tuned. (post graph later on).

Dyno Tuned = "350rwhp" pretty much on the money
tq = about the same.

 

it's also Matt murphy(owner of GMMG) who feed's he's black bird owner's with bull **** saying they destroys Z06s and that they all dyno at 350 rwhp and the was he's like want an extra 75 hp that will be 7 grand for some 425 sticker's on the hood all he say's is the car comes with cat back whisper lid but it make's 380 hp

 

yes, it is a dealership hotrod.
this is all that you need to know...

that is one sexy car

blackbird-TA, 350rwhp is a bit optimistic. my car only put down 343rwhp with a lid, MAF, LS6 intake manifold, longtubes, and dual cutouts on the y-pipe... and that seems about the average for other cars with similar mods.
after all, shorties don't gain you much at all.

 

what you beat on the street has a lot to do with power jackass, and gearing, weight, drivers. blackbird

 

actually it has ALL to do with the driver.....think about it..

 

Just FYI, the 05 GTO's don't hook worth a crap. It's not uncommon for guys to go high 13's or low 14's and spin the tires. It's funny on the GTO forums to listen to guys pissing and moaning because they can't make the car hook. Stock 05 goats are putting down 330 to 340 at the wheels stock. To make a horsepower estimate based on what you think another car has is a bit of a stretch in my book. Go spend $100 for 3 pulls somewhere and find out.
