I thought it also had to do with metal flying through the tunnel... !?
Isn't a solid shaft dangerous, while CF, will just splinter, and destroy itself, yet leave the tunnel in tact !?

 

A solid metal drive shaft can possibly brake off and do some serious damage to the under carraige, possibly hitting the rear wheels and doing more serious damage.

 

No you don't.

Plenty of people have already hit upper 11's on the stock fuel system.

 

The stock fuel system at the limit.
My stock PFC map gives me like an 85-90% injector duty cycle.

I mean, it CAN be done, and I've seen people do it, but I'd upgrade the fuel system anyways just to have a larger safety margin.

 

Well, I'm not going to type my thoughts on that again, but here's where I did once before:

I'm was running 14 psi on stock ECU/fuel setup. Now I'm running 16 psi on Haltech and stock fuel setup.

 

thats a good time for those mods...what was your trap? can u psot a time slip?

edit: now i read you are claiming trhat time with a 2.2 60' tiome...i call bs.

 

this was the posted mod list for stock turbos = 10.98@130mph

[ET street tyres, ported motor, non-seq twins (peak of 18psi), ported wastegate, JDM 95- y-pipe, power FC ecu, trust 3-row intercooler, trust cat-back exhaust, straight pipe, downpipe, trust pulleys, trust elbow (intercooler piping --> throttle body), upgraded clutch, turbo II diff, upgraded axles, upgraded springs/shocks, hi-6 ignition, 255l fuel pump, 2x850cc + 2x1200cc injectors]

 

This part should be in bold to get 11's .

 

drove my rx in an streetlegal drag a couple weeks ago. had an reactiontime of 0,65 and 0.55 on my second run.

 

Dai oni what clutch were you using?
Do you still have a copy of the map you were running. If you have im willing to buy a copy off you for a base map for my car

when my car stock i ran a best time of 12.98 @110 with like a 2.1 60' and a 250lb idiot in the car with me. had the basic bolt ons..dp.md (no cat)cat back,trust fmic,intake,M2 ecu, and running a max 13psi ......so maybe a bigger fuel pump slightly more boost and a better 60' time oh and no 250 pounder in the car with you and low 12's maybe very high 11's are within reach with drag radials or some mickey ET streets......theres my whole .02 worth

 

I ran a 12.62 @113mph on very bad street tires with a 2.2 sec 60 ft. at .9bar Now changed my tires and getting 1.90 sec 60 ft with only .6 bar. Need to get a decent run it asap

 

ran my car with shitty tires and a worn out engine.(6 in front and 5 in rear) Had intake, DP, MP, catback, PFS at 13psi, pullies. Ran a 12.7 @115 with a very shitty 2.4 0-60 ft. Now im about to get back my car with a fresh ported T-78 motor with lots more fuel!

 

"Dai oni what clutch were you using?

not my car.

also - get a real tune - a borrowed map is like throwing darts blindfolded
