Default Hp Guess?

I did a 02 wrx swap to my 95 brighton, "Nice and light" so i now got like 300whp with a standard upgrade to pink, 255 pump, vf39, big tmic, perrin rails, v2 ap flashed, catless exhaust. im going to change everything and am putting in a sti longblock with dw1150cc injectors, 255 pump, rails, fmic, rotated mount perrin gt35r setup, tgv deletes, flipped intake man, i think that was it. O and going to run 24-26 psi with race fuel.

So what you guys think as far as hp and 1/4 mile times

now the real question comes to drivetrain and tires...
non-driver in the 11's, 10's would be normal and get it right, you'll be in the 9's...

regardless you should be getting the boot from the track, as I don't see a cage in the list.

How light is light? 3000lbs? 2800lbs?

Say your car did actually have 300whp and weighed 2700lbs (with you in it) and you managed to launch without breaking anything and driving without missing any shifts, you could manage a 12sec flat at approx 112-114mph.



EDIT: I think I misunderstood your post lol. Do you want to know the potential of your current setup, or of the setup you are considering? Anyhoo, when in doubt, just use one of the many online performance calculators (like THIS one)

I am going for a tune with XXX mods, what will my WHP be? Let's follow the chain of factors: your tuner's ability, the type/condition of your spark plugs, your fuel octane, the temperature, the elevation, the humidity, the dyno SAE correction factor, the dyno type, whether it's a loading dyno or not, your mods, whether your mods are working properly or not. Let's say Timmy in Colorado says you should get 240 WHP with those mods and your session in Califiornia nets you 210WHP. Guess what? 210 WHP is all you are ever going to get and second guessing the tuner seems to be your only alternative when in fact you should second guess all the factors above as they all play a roll. The fact is your WHP figures are your WHP figures and there is not such thing as average when it comes to dyno figures except for possibly 100% stock vehicles.

I am going to the track with XXX mods, what will my 1/4 mile time be? Very similar to the dyno question above. What type/pressure tires are you running, whether you run through the water box, how much experience you have, where and how you launch, your gearset, your final drive, the temperature, humidity, elevation, mods, and tune are all variables. The biggest variable is the driver as if you use the same car with 10 different drivers, you will end up seeing 10 different times with a band of times about 3 seconds wide or worse. What Joe in Alaska runs with identical mods bears nothing on how you will run in Phoenix as even if you flew Joe in to drive your car, he still wouldn't have the same times as he had in Alaska.

Anyone else have anything that is unanswerable?

Do the complete install, get it dynoed, weigh the car, come back, and then we'll talk. Until then it's all speculation, and even AFTER that we'd still be just guessing, but with at least somewhat of a reference point.
