you're the other guy on here I was thinking of that was running 12.5's @ 110+ with a non-excessive bolt on car.

 

Woot woot!

What gains would I see from a set of 1.6's? Or maybe even 1.7s?

From your personal experience that is....

 

Second to the long tubes, the 1.6's were one of the best gains in performance I noticed. Lash them on the loose side and they are awesome. You would have to change springs to go with 1.7's and I can't speak to how much of a gain over 1.6's that you would see.

 

Definitely not the norm.

Congrats.

 

Nice Times!

 

Get some LT4 springs and 1.6RRs.
Remove as much weight as you want.
They will do 115 (atleast) with just bolt ons!

 

Thanks guys.

My car weighed 3420 with me in it last time I checked.

Are the 918's better than the LT4 springs for a weekend car? My goal for this car is to NOT become just a track car. I want to keep it as streetable as can be. I realize valve springs aren't going to make it not streetable but as far as wear and tear (since the LT4's are factory stuff) how often do they need checked. When referring to the lash. I had planned on doing the RR's and EWP over winter. Along with new brakes all around (been needing these for awhile) so I need a good project to get me by for awhile to pass the cold season.

 

918s are good and would be lighter than the LT4s but cost more.
LT4s can be had for $50, the 918s are $170ish and the hardware for them can be had for $150. Just depends on what you want to do.
If just running the stock cam and 1.6RRs then LT4s will be good. If you plan on running a larger cam SOON then go with the 918s but if it will be a while then you will replace the springs with the new cam...

 

With lash, I go just past quiet when adjusting, screw down the allen lock and then about 1/8 to 1/4 turn of the nut to lock it down.

And I agree with Shon, anything more than LT4 springs isn't necessary if you are just going to do 1.6's in the foreseeable future.

3420 with you in it? Wow, that is pretty light already! Mine was 3640 with me and a 1/4 tank of gas. I was never much for taking stuff out of the car though, only thing I removed was the spare and jack.

 

For what it matters, I got my car dyno'd again on the same dynojet.

Stock it did 257/290.

Did 304/336 this morning.

Definitely not 100whp higher than stock!

 

Amen brother.

 

Those cond. are awesome.My local track here is 1600ft.above sea level, i didn,t get a d.a reading when i ran my times.Those 6 spd. cars used to run 101 mph trap speed stk. so your mods can relate to what your running.I had my 94 down to 3490 wght. w/me in it by removing spare tire/jack ,other loose things like owners man. etc.Also ran w/1/4 tank fuel.
