porting the intake and inj housing, headers, good exh, and custom chip will take you a LONG way with a good running zr1. if you have the extra bucks, pull the engine, port the heads and have the cams timed.
the zr1 is stout from the factory, but has room to build lots of furry little ponies if done right. not the cheapest engine to mod, just the best.
my LPE 368 wasn't cheap (but thank god I didn't pay for the mods) but does 536 HP at 7500 rpms with a very flat torque curve and a wide power band which is what makes all the difference.
hey pete, those are some good 60 ft times, especially on the GSC's!!! what rpm do you launch at??/ I don't have that much dragstrip experience with the zr1 and those times are very impressive for the small mods.
My sig doesn't mention that my Z weighs just under 3400 lbs
with me in the car.
About those 60ft it doesn't mention that i go thru 2 sets of clutchs a season cause i kind of ride the clutch out,basicly i hold the revs at about 3500 and release the clutch slow while mantaining the rpm's (since i have the stock 3.45 gears),
and i powershift.
I have run 11.90's twice the rest of them were 12.00's and 12.10's on GS-C's temps were in the 50's.
On another day i borrowed a friends DR's and was running in the high 11's, 11.80 was the best.
I always look at my MPH to see what power the car makes.
Hoping to be a little faster this year.
Not much more to tell, just takes time to get everything properly aligned and all the LPE glass worked smooth & trimmed properly. It requires modifying the turn/fog lamps to cut off the fog lamp section, seal the housing & make inboard mounts as the front opening would expose the fog lamps. Rear side clearance lamps are deleted due to the "vents" behind the rear wheels being identical to the front, contrary to what is shown in the LPE photos. Must be a slightly different version. Rear end is awesome. Going to delete roof mount brake light in favor of LED strip about 12" long in center of spoiler. Makes for a smoother look. Toledo Pro hood is a really nice piece of glass. Painted underside same as exterior to make a bit more showey when hood is up.
Looks even better in real than LPE photos do! Anyone know where or who owns the other 3 LPE Aerobodys? One red one for sure, would like to know what color the other 2 are.
Several other mods including wheels/tires/brakes/engine & interior are following as soon as body is done.
Hope this is of interest to you & thanks for asking.
