Looking for power on a budget... Nitrous???

i read a mention of the rear mount turbo system in one of the registry newsletters but beyond its existence, i really dont know anything about it. i will look into it. i just got it back yesterday from having the exhaust and headers and light weight fly wheel put in. the car sounds amazing!!! the car used to still pull hard in the upper RPM range but it felt like the car didn't want to rev past 6k. it would if i kept it in gear but after six, the RPM needle was quite sluggish in its climb and i think the altitude here has a big thing to do with that. now though i can visually see the RPM needle moving through the upper RPM range faster. infact, i bounced it off the 7200rpm rev limiter for the first time today. ...oops. lol.

Chris/ I have a 364 inch motor in my 91 /dynos in the 440/450 range,gets 24mpg. with 4.10 gears/has complete jeal motor/runs hard over 4 grand/ as for turbos I just bought a 05 fidanza t.turbo car/they had the turbos on a stock ls2 with headers and made 625 h.p. before blowing it up. the new motor is a built 402 cu. in t.turbo 975 on a dyno,pulls like a freight train from 2 grand.While I love the twin turbo,roller cam sound,the zr1 sounds better.And whatever you do remember a chain is only as strong as it's weakest link. joe

Thanks for the input joe. interesting information about still getting 24mpg with 4.10's you cant go wrong there. maybe i will consider a rear gear swap. is there any data to show how much a 4.10 gear setup decreases ET's?

4.10's will help out, considering your altitude into the equation. best bang for the buck, bar none

i dont really want to loose any fuel mileage and it would be nice to keep the top speed capability up there although i will probably never use it... but 4.10's sound pretty fun. would really be interested to know what that upgrade would do for Elapsed Times.

what about bigger injectors or a better ignition system?? would either be much of a HP gain?

chris , i have 410s in my blk 90 with ported inj housings and plenum,jeal headers, spin tec exhaust with dr gas x pipe, fidanza flywheel , car on drs has run a couple of very high 11sec time , runs 12.10 30- @ 119.85 to 118.00 all day long. there are 6 vids of my car on u tube if you want to see what the result is . under bradley taylor zr1 @ famoso car gets 24-26 mpg on the freeway cruizing between 75-80 . i have 3.92s in my callaway 475 snat zr1 that just got headers runs about the same times but 3 mile an hr less and gets 25-28depending on if i have the cruize control on . the black car gets better gas milage now then when it was stk (22-24). on injectors you dont need bigger ones until you get into the 415 zone . there are those who own them who are running the same size as stk . if you have the factory inj still in you car getting them replaced really helps out . jeff would know better on the ignition if there is a way to upgrade it . hope this helps .
