Re: apr stg3 guys, what do you trap in the qrt? (tim18t)

about 112-116. However that depends on if you have the base APR kit or if you have tweeked with the boost, turbo, exhaust system, type of tires you are running etc. Running slicks can reduce your quarter mile time by as much as 1-2 secs and larger rims will also slow your trap down. With 18" on I run 14.8's at 98mph compared with 13.8's at 103 with 15" slicks - that is with a K03S turbo though. So you should be well above that with the GT28R.

Hi Tim,
Witha 98 mph trap you likely need some help.
If the car checks out mechanically I would try and dyno it vs a stock car and a car with the BPU's(BasicPerformanceUpgrades).
At 98 mph it is unlikely to be making more than 220-240 crank. Good luck on your search.
Jeff

Re: apr stg3 guys, what do you trap in the qrt? (J. Moss)

it seems to be making good power
the boost comes on strong and peaks at 26-27 and holds 20ish till around 7000 rpm.....i just dont understand!

Your on 91 oct being in NV, this is just a guess...If you are on the stock IC and boosting that high on 91 its very possible your ECU is pulling timing like crazy.

You should be at about 105mph, maybe even more with the cold temps and the FMIC.
Maybe there was a headwind or something. But regardless, 99mph to 102mph, something aint right.
Get on the dyno again.

Re: apr stg3 guys, what do you trap in the qrt? (new 337)

Best trap I had was 112.
Stage 3
FMIC
104 race gas
Drag Radials 205 50 15
60 degree temp.
Full interior
2.5" cat back
stock axles, DV, N-75, and airbox
Best trap on pump gas is 108.
Stage 3
Stock Intercooler
94 octane gas
Drag Radials 205 50 15
60 degree temp.
2.5" cat back
Full interior
stock axles, DV, N-75, and airbox
Oddly neither of these traps where passes that netted my best e.t.'s
Good luck sorting out your woes...I think it is your clutch and 91 octane isn't helping either.

On 205/50/15 the 4th gear roll-out ratio puts you in the sweet spot.
with 225/45/17 expect 104-105mph on 93 and 109-110mph on 104

Tim...bring it over to my house. We'll do a third gear punch on the freeway with my car and your car and we'll see if your car can hang. If it can't, then we'll at least know that something is wrong with the car and we can go from there. What octane were you running at the track?
