Default Horrible 1/4 miles times after rebuild/turbo upgrade and retuning, can somebody suggest anything!!!!

Ok guys heres the rundown, this is the setup of what i had before:: 98 gsr in a 93 si hatch,,, full Drag gen 3 kit on it with the 50 trim turbonetics t3/t4 on it, msd 6al, Hondata 2b, 550cc injectors,,sti rail, 255 lph FI pump, Tial gate, 2.5"DP, 3"inch exhaust,, ok now this setup after hondata and tuning by BOOSTED-HYBRID, put down 283whp, and 212tq at about 9.5psi after 9 dyno pulls (heat soaked) A/F was at 12:1 charts were perfect!, stock bottom end, stock head gasket, stock head, car also ran 12.80 @ 108mph, on a 13" lenso with a small 22" slick, weighing in at 2447 with me in it,, (im a big dude) ok so get the point here now,,, then about a week after running it, i blew the rings in cylinder 3 because it was later found out that there was a 3" piece of rubber fuel line in the intake plenum near the intake valves of cylinder 3, and the original turbo i had blew its seals, and had a bent shaft,,,, so it was time to upgrade,,, heres the new setup::::
98 gsr head,, 95 gsr block, stock internals (both) this is what is new: skunk2 intake manifold,,, and a turbonetics t3/to4e 57 trims .63 a/r turbo,,, all togather on the same **** i have listed above,,, also i took the MSD out, and went back to the stock ignition,, msd kept blowing out the ICM or something,, Jeff Evans (boosted-hybrid) once again tuned my car in the street, no dyno time, set up pretty conservative, he pulled about 2 degrees of timing up top, and the a/f was about 11.5/1 this time till i got my 3" DP and leaned it up a bit,, so anyway Jeff cleaned everything up,,, did a compression test on the rebuilt motor,, 180 across the board **cold** car pulls hard as hell, faster then original setup,,, so i go to the track expecting some low 12's on my shitty slicks,,,,,,,,, then i almost commit suicide!!!!! f*cking 14.1 @ 97 mph????!!!!!!!!! I was like what???? my car was pulling hard as hell to Englishtown, and leaving I simply dont understand this at all,,,,, my hatch did that all motor can somebody tell me whats up,,, i mean i raped this maxima that did 15.4 @ 88, by like about 8-10 cars, could the clocks be off at Englishton??? i dont get it there is no way that 2 degrees of timing, no msd, a bigger turbo, and a skunk2 intake mani, with tuniing for that, can loose 110 something HP,,,, i dont get it,,,, all my intercooler pipes are good, all the vacuum lines are good, turbo is holding boost, no spiking or creaping at all,,,, car is pulling hard as hell on the street,,,,,,,, and this 14.1 was ran back to back, how is that possible,, my speedo red over or close to 110mph, but i was on a 13" whell with a 22" tire,,,,,,,, i dont know please help me out here guys

Answer is yes the clocks can be off, although a mxima at 15.4 sounds close.

First, take it to the dyno with a wideband, make sure everything is good (power and A/F and Timing)

Then take it to the track again or a different track and see what happens.

The car was dead on with 11.7~11.8:1 air/fuel, the timing is at 23 degrees total at 9-10psi range. The car pulls hard when we were street tuning it, my best guess is whp output is in the 275-280 range still.

A 14.1 car running a 15.4 car will be like 10 cars. You have the power but is it taking forever to spool up at the track? Your mph suggests your not making anywhere close to 280hp.

how do you figure that 15.4 to a 14.1 would be 10 cars?? no way think about that,, his mph was like 88mph too,,, no way i raped him on video,,,,,,, and i might have found the culprit,,,, my slicks were on about 6psi on a 22" m&h tire,,,, they were flat as hell,,, and i think that the rim could have spun inside the tire, i.e. broke the bead or someshit,,,, after i got back from the track i noticed that i could push air out of the tire by hand,,,, i dont know im mad pissed off here,,,,,any other suggestions??? and its not like im running a friggin t3/60-1 on my **** or anything the spooling is a little laggy but not ******* 100whp worth!!!!!!!

Dude chill out it's just a car, lose the attitude Just because you raped him on video doesn't mean your times are wrong. Heck if you have it on video go back and use a stopwatch and time the thing yourself.

You can beat around the bush and blame silly stuff like the slicks on the rims or the tracks timing but your just avoiding the obvious that some where your losing power. Take it to the dyno again and see what the problem is.

ok dude im not bing a dick to you but how do you figure there is a flat spot in my tuning where i loose up to 120whp??? i put down 250 on 5 psi, do you know who Boosted Hybrid is&gt;? do you know his reputation,, his tuning is precise as hell, i dont know, but you are right i need to get to a dyno to see whats up,,, thanks for that though, i mean all my boys that have drag kits have the same upgraded turbo and there is no problem at all,,

Didn't you say you had a engine failure after the first dyno run? Maybe something happened between the last dyno run, the rebuild, and now.

ok now heres an update,,,, i ran this mustang tonight that went 12.40 on his street tires as he was tonight,,,, and i beat him by 3 cars, we raced exactly a 1/4 mile and my mph was about or a click above 110,,, so i know my **** is on point,,, i want to get to a dyno but boosted-hybrid is back at school and cant do any tuning till winter break,, so until i get some dyno time i will believe its my slicks,,, i looked at them again,,, my 13" lenso and the m&h 22" racemaster that were on the right front wheel were completely flat in my garage, i could push on the tire and air came out,,,, Everybody into this game out here who looked at my tires and knew my setup said the culprit had to be the slicks,,, the rim had to have spun in the tire, or they lost all thier air by the time i staged the car,,,, thats the only thing here,,, but until i get to the dyno,, i think my **** is ok,,,,, going to etown, on street tires on wednesday night next week hopefully,,, went 13.5 @108 at 8 psi last time, with shitty 2.4 60ft times so we;ll see,

I usually ran about 12 psi of air pressure in my 22x8x13 slick and I pulled 1.78 60' times. I think your air pressure was way too low. 6 psi of air pressure would kill your top end. Try more air pressure and see what happens.

What up Dave, I got your message last night. Could it be that your clutch was spinning? We raced my brother's hatch at Atco last Sat. and for the first 3 runs the clutch was spinning hardcore. We let it cool down for 2 rounds and it seemed to be okay after that. Thats all I can think it could be besides the Lenzos spinning inside the tire. From what you say the car runs hard, and I don't think the clocks could be off.
Another thing is that if you didn't have a lot of tire pressure and you still have that front lip spoiler, because the car is low the spoiler could have broke the staging light first before your front tires. It happened to my bro's car. That could take up a little time too off the clock. Either way don't sweat it, the car runs hard and you can enjoy it. The only real way to tell it to take it to the track and try again or take it to the dyno. Good luck.
After I come back from InlinePro with my car we'll line up...HOLLA!
