Decat pipe:
Really am very impressed with 519 Automotive, i've been around the specialists in my time and am a professional mechanic myself so know what company is worth my money and which to avoid. Apparently its owned and run by a sole engineer, Daniel, and that makes for a very personal feeling. He took time to discuss the work before i left to ensure i was happy with everything and answered any questions i had ( We decided against the paddle clutch at the last minute! ).
And as promised he did the entire job in under a week so i could have it back in time for drag race weekend. Would recommend him to anyone after services to full engine builds. Thanks mate
So what can i say about the differential? Its hard to put it into words but this car will not understeer now! The backend actually breaks away before the front, on three occasions now i've gone 197 drifting lol
Launching it i still spin the wheels on nitrous but its more civilised to control off the line. But for pure cornering ability its the best mod i've ever fitted to any car.
The clutch is a little harsher on the bite with less feel and ability to slip, but no heavier. Makes pulling away interesting with the 197s poor throttle response lol, thank god i didnt go for the paddle clutch.
Engine mounts are a nice addition, not too stiff or harsh to the point of uncomfortability but makes lauching that little more precise.
Lighter flywheel. Hmm i got to admit this hasnt aided acceleration at all but the quaife diff was much heavier than the OEM item so i havent actually lost any transmission mass. Its most noticable when changing gears as the revs hardly drop a couple hundered making fast shifting much smoother. Result.
Manifold decat. With a fully decatted system the car has a horrid flatspot again which even the remap cannot smoothen out. Its barely louder than with the one decat unfortunately but the car definately has more torque across mid range and picks up much quicker. Feels less strangled at higher rpm too, although seems to feel a little flat at 7000 to 7500 rpm now.
I'll leave on a final note of saying before i was like 'oh dont want to use my car this weekend it might get caught in the rain or put too many miles on it'. Now it feels so much more focused as a drivers car i think 'cant wait to get home tonight and take it for a half hour spin with nowhere particular to go lol. Go Kart for the road FTW
I think that covers all my reviews, if anyone wants more info please let me know. Thanks.
