No prob, I'll pm it to you

It's a little bit more track oriented, but still just as drivable as it was before. The 18" ZO6s are gone and are getting replaced with 17x7 and 17x11 streetlites, I've got a set of MT 295/45 17 (27.4" tall) that are going on the rear. And I've done some serious cosmetic work under the hood. If fact, the motor is out of the car right now because the engine bay is getting welded up and repanited. Plus lots of little other stuff...

Should hopefully be a decent set-up for the Extreme Street NA class at the shootout,

I hadn't even told anyone about the new cold air set-up that I made, but when I saw you mention that you were gonna do the same thing, I figured it was time to speak up. I've got lots more pics of it, from start to finish.

weight wise:

Strange brakes front and rear

PA spindles which use 1st Gen brakes which are lighter then the 4th Gen

manual brake conversion

guess is 100ish lbs and I will try to scale the car again before the next track day

plans before next race day is to put the car in a bit more of race mode :

-pull the catback and run a dump off the Y ( approx 50# loss ).

-pull pass. seat ( 28# loss )

-run a short belt for no PS ( no loss )

-try a 28" ET Drag ( approx 25# loss )

-pull bottle ( 25# loss..was full )

I can not touch the race weight for the shoot out, so I have to find little things to get me closer to the 3100#.

+ we are going to build a new induction hopefully before the weekend which will go over the radiator and into the nose with a large filter. I should see some good air and gains being that I have no bumper support and the grill is wide open. This would be similar to a LS1 setup + a FTRA, but even better.

I am really liking this NA setup and going this fast.

N20 is setup, but need to get it on the dyno to test first
Nice job Larry, can't wait to see how the new intake works out. As we talked about a while ago, I'll be trying the same thing.
PS, finally fired the car up a few days ago, been sitting since that last track day, Nov 1st.

Larry---
On second thought I think we'll pass on the lineup (EVEN with spots!)

That thing's hookin' AND haulin' for NA and Radials...

It took a 325hp shot to get that kind of MPH out of the IMP!!!!

Very nice!
Get it into the shootout.

sounds like I have some show car competition I'm sure the car is going to look killer.

Thanks Rick

I'm hoping this style intake will really pick up over just the LS1 lid style. We plan to go back out this Sunday the 19th if you want to blow the dust off ole girl.

Well I'm not sure it's quite up to par with your car, but I do the best I can working out of my little 1.5 car garage

But I will say your car has given me tons on motivation on it

I don't have any hard evidence of gains, probably never will because I changed so many other things at the same time... but I can tell you I noticed a bit if difference with the butt-o-meter. And better throttle response for sure.

For comparison sake, before I had a K&N CAI with a 1le rubber elbow.

The sound quality seems bad since loaded on you tube for some reason.

tape on front end was a little test, but got no true results since I ran the cutout open this pass compared to last without the taped up grill

+ .46 mph

my father was trying to get my attention to say I was a bit out of the groove, but it still went o.k

hope you guys/girls like it
