Any pictures of the "after"?

Thanks

Brad,
I'm a little confused, which in reality is nothing new.
I noticed in another post, you, posted some very very good ET time slips
and stated that, Corey had ported and set up your car. along with dick
gulstrand, tweaking your suspension. but now your asking for info, on
porting your car. Do you have more than one zr1. ??
You also stated that you have been doing cam timing work.??
could you elaborate on that statement, for those of us, that are looking for a few extra ponies.
i'm not trying to pee on your cornflakes here, but the numbers you have posted, are better, than many of the fully ported, chipped, headers, exhaust, and shifter dr. equiped cars. My car is stock other than, headers
corsa, 410's , a pair of fuzzy dice, and my best ET at Bowling Green
was 12.72.. what type of tire are you running??
maybe i weigh more than you... ,

No! I didn't take any pictures, but I just ordered a new modded e-prom from Marc Haibeck and when I install it I'll take a few pictures.

no problem to clareify, yes i have 2cars numbers 1564 the blk car bought on 8-04 and the red car number 2924 bought 12-05 . the blk car is the car with all the work done to it and the car I race . it recently had the heads ported by a friend , the cam timing was set the factory way, another friend tuned it after the head work . corey henderson ported the injector housings and plenum and did the original tune the car in that state made excellent power the figs were 409.9rwhp and 373.3 tq with a flowmaster exhaust and jeal headers. I did some playing with the exhaust and before the head work the figs were 426.8 and 381 2.. i was very happy with coreys work and his tunning abilities are second to none. the car in this state ran a best of 11.88@119 @famoso in bakersfield . the new time are a result of the heads and suspension improvements . I hesitate to share all thats been done on open forum due to the abuse that follows . i have been wife ordered (rightfully so ) to keep it simple and those that would like to find out more in depth info to get ahold of me personally. basicly she said who do you race your car for them or you . since i race for me and i love her , plus hard to dispute her logic. she is jealous that my car is so much faster and wants hers done , but cash being a little tight right now thought that maybe i might be able to do them myself , but i will listen to those wiser than me and send them off .I also have an extra drive train that i can play with . bought a low mile engine trans and rear. so i guess that can keep me busy . but i better make my redheaded brides car faster by spring . she wants to go drag racing too. heck she got in it and first time out with the current setup ran 11.75 with a1.86 60 ft..I mean she had never been down the 1/4 mile before ever. just love my tomboy bride .proably better than me. eek opps the tires I am running mt et street radials . I am also going to try some 390 gears at dicks suggestion

yup ,we put the marshmellow(her knickname for it ) in the red car . had to use theold inj all the electronics and wireing out of the red car plus water pump and alt ,air conditioner, plus replace the crank seal . and she thankfully purred like a kitten . now she wants the ported injector housings and plenum headers . my wife i think is a bigger car nut than me so i guess the work will never be done . but thats ok dont have to beg for cash for the cars , which is good by me.

Yes, I've ported my plenum and injector housings... The first time I went into the plenum, I simply took out the casting marks and port matched the plenum to the IHs... My Z went from 318 RWHP to mid 340s on the porting alone - roughly 25 RWHP gain. After adding headers and adjusting the chip, I made 372 HWHP at SGC in 2004. After seeing a few other porting jobs from some of the known porting guys, I decided to go deeper and siameese the plenum and open up the IHs to 36mm. While I have not dynoed the Z since my last round of porting a few years ago, I believe I've gained quite a bit more RWHP, but at the expense of my mid-range torque. Looks great on paper in that I could never use all my mid-range torque with the 4:10 rear without spinning tires. Now I have a different "problem"... I don't spin tires very much in the mid RPM range, however the rear tires break loose in the upper RPM range.... so at 55mph, I lose traction. Seat of the pants, it is much faster in the upper RPMs, but I sure do miss the low/mid RPM torque. I may be able to work it more in the chip, but have not had time for it... Before you get started, you need to ask yourself what you want from your Z.... Believe there is some give and take with every mod. I've attached a few photos taken along the way.... I used my trusty die grinder, the bits in the photos, and my homemade 36mm porting ball... the red line around the ball was made with a red sharpe and left a mark exactly where I needed to grind to make a uniform 36mm port job.

Before I get flamed, I know there are much better porting jobs out there, and done by better experts than I, but I enjoy doing these projects.... May not be as good as others, but better than some I've seen... It's my Z and I take the time to it the best I can.... I hope these photos will help you decide what you want to do.

Not following that, are you selling your cars?
