limits of walbro 255 pump, 600hp
-
very true, it is dropping for sure, hell, the more i think about it, it might even be a walbro 307, thats a little weaker in the high psi ranges than a 340, but its been years since i bought the damn thing.
And magical thoughts? a 4l80E transmission has the ability to read input shaft torque, it isnt magic to turn a torque # into a HP number, every dyno in the world does it. And, there is no way to fudge the presented input torque, also the calculation is the same one used by every dyno produced, so if what the tranny in my car sees is magical, then i guess every dyno sheet is magical too. Look at any STS, rearmount system, on a stock car, say a LS1 camaro, dynos 320whp stock. STS on 8psi? if you cant get at least 420whp out of that, shoot yourself. thats a solid 100whp gain any day of the week, well a 100hp gain on my motor is AT LEAST 540 crank hp. Get a life.
On the other hand, there are so many turbo LS1 f-bodys and vettes that get over 20mpg, i wont even get into it.

I beleive everyone was thinking you were refering to whp #'s, not crank.
FYI, I plan on making ~500 RWHP on a walbro 255 this year. It's not a standard walbro, it's a racetronix. I beleive it is modified to provide a higher fuel pressure. I firmly beleive I won't have any problem with making that (almost 600 crank).

and gets how many miles to the gallon.look at his teg for instance. That car is pretty damn fast and its a 4 banger Ibet if he drove it as a DD(not sureif he does or not) but i bet he would get over twice the mileage you do and still go as fast at the track:icon_thumleft:
i dont believe he made this thread to compair who gets better gas millage, it seems alright to me, as for you go buy a geo and be happy

So what is 540 crank HP to the wheels through a 4L80E slushbox? 90 hp less?
And I should probably shoot myself I've only made 311 HP per liter so far, and I am only on pace to make over 400 HP per liter this year. Man, imagine what us stupid 4 cylinder guys could do with 6 liters! Haha.

Remember gsr horsepower means nothing if you just sit at the rev limiter all the way down the track.... i can see it now no traction ever... but did you see my sweet 400hp per liter..OMGHI2OH

Grr:
- If I had rich parents that helped me mod my car, that would be sweet. I too wish I had rich parents.
- Rotarys could technically be treated as 2.6L motors due to their design.
Traction is difficult, but I guess we'll see what this year has in store. Chassis work is sweet.
-
Can anyone barrow me their rich parents for a year? Please?
Oh dang, guess I will have to just pay for it myself.
Also, I beleive, and correct me if I am wrong, nicks cars has clocked a faster 1/4 mile time, which really is the only thing that matters....

BTW, it is a walbro 307, that is sooooooo gay. Im actuall kinda pissed about it. On the buick board, they say 550hp with a 307, 640 hpwith a 340 i guess a nice new walbro 340 should be good for another 75hp than this shitty 307 with 40k miles on it. Damn it anyway.
-
i could give 2 flying shits about anyones times, i built this car for me, the way i wanted it. With no cage, and a assload of torque. BTW, logging the tourque input shows a sweet 600ft-lbs+ from 3500-4200, im gonna put so many miles on this bitch its gonna be sweet, and i wont put a bar in it anyway, so timeslips mean nothing

have u seen gsr's 60 foots? have u drivin a truely fast car? i know the answer to these by ur comments in ur post. driving a 10 sec car is a little diff then ur 15 sec car. did u know that holding a turbo 5 speed car on the rev limiter through the shift holds boost pressure? which in return brings little to no turbo lag? but then again by ur comments u have no idea whats ur talking aboutthere is alot of assumtions about nicks car. yes he makes a lot of power, yes that much power in a non fwd street car would provide faster ET's

your such a fag, zac can probably make 450hp/liter, big deal, i have all stock shit. wish i had rich parents.so how are ur measuring flywheel TQ? is there some magic genie hanging on to ur crank telling whats going on down there? these are outragous bench racing claims at best
and speaking of the rich parents thing. how much did u pay for ur gto before ur burnt it down? money is money just becuase he has an older car that he decided to put money into modding it instead of buying a brand new car for the same money doest mean he had parental sponsorships, ive known nick for a while and i know what he has done to the car the last few years and i know that his parents are not footing the bill. i think he might be getting a little old for that by now anyway
2 more people for my long list of D-bags

have you ever been inside a new computer system? obviously not. new computerized trannys can tell you all sorts of wonderful things. Its read by the computer in any OBD-2 equipped GM vehicle, and ford, and dodge. how do you think traction control systems, torque reduction and ABS systems work. Its all in there from the factory, so magic genie your own shit.
Fast 60's eh, it better be WELL into the 1.4 range to be considered fast, especially on slicks, i did high 1.6's in this GN when it was BONE STOCK, with sticky street tires. If anyone is a d-bag, it is you sir. -

If anyone is a d-bag, it is you sir.please try not to explain on board computers to me, im a ase and gm certified tech. i daily work on vehicles with with up to 25-30 diff control modules let alone training with hybrid vehicles
what exactly is measuring rotating force (aka torque)? yes i understand u can get an estimate with input and loads but like i said estimate
speaking of being a gm tech, i work on gto's once in a while and ive never had a dealer serviced one randomly burn to the ground? so my question is why would a newer vehicle like this burn to the ground other then faulty installation of a after market part? maybe a n2o kit? hmm i think we should all be taking advice from somebody that cant safely work on a vehicle with out sending it to the scrap yard
hmm yep proving the d-bag theory once again

So, what is going on in this thread? First talking about maxing out a fuel pump, now this has turned into a thread compairing E-penis size.
Who gives a shit, let him think what he wants, if he is proved wrong later, so be it. Also dealerships don't always to the best work you can possibly get, yes they are "factory trained" or what ever, but they still dont always catch everything or get everything back the way it should be.
