So I have a 99 FRC that I have had since 2011 and when I bought it it had only a vararam intake and which I believe a hurst shifter. first I added the B&B Bullets then I added some 1 3/4 Dynatech Supermaxx headers with gutted cats, a LPE 160* stat and a ECS Mail order tube. it had dyno'd with 331 rwhp and it was running real lean at 13.99. I also added a mantic single clutch and I broke the rear and had it rebuilt at Horsepower Addicts with C6 Z06 out put shafts and I have the stock 3.42 gears as well.

The car Should be put back together next Wednesday and maybe 2 weeks after that tuned by Horsepower Addicts in Delaware. my question is what does everyone think my numbers will be once everything is said and done?

I just added 3.90s to the car and wow it feels good with them.

Car made 440rwhp 403rwtrq before the 3.90s. I'm adjusting the tune here and their now since the tune. I have put a new maf sensor in as well (2/19/22).

Well I broke the main output shaft from the trans to the diff. Diff was still good so i dropped the trans and pinion gear off at rkt performance and had him build the trans, add a 30 spline and changed over the pinion carrier to the c6 z06 unit as well. I even just ordered the MGW shifter as well. I am getting rid of my Hurst billet shifter.



The lip that needs to be cut from the widebody fenders. As you can tell it was rubbing pretty good once I put the coilovers on.










Car ran an 11.93 in the quarter just don't remember what my trap speed was.

 

I'm gonna say + - 420ish

 

440. Good luck, don't get hung up on dyno numbers, get that thing to the track.

 

Well the third time i had ever taken a car to the track was with the vette. This was at cecil county in maryland. Nothing but bad wheel hop and myself just dumping the clutch instead of slipping it i ran a 13.1 the second run. 3rd run i broke the rear and that was 2 years ago. First time i went to the track was at a track in arkansas with my stage 1 superchraged civic si it ran a 11.36 in a 1000ft. Same track i took my stage 3 evo 9 mr i ran a 10.35. my 1000ft in the vette was 1 second slower than the evo. So hopefully this year i take the vette back and run it better than the first time and i see some good numbers.

 

I understand not wanting to get hung up on numbers but for how much i have spent i hope im more around 440 than 420. I know its not much of a difference but it is when u try too look at everything in the picture like porting the intake and getting a ported tb to squeeze out more before spending more money on other things.

 

Mph is the best dyno there is. After it's all said and done see what mph it does in the quarter and you'll have a better idea or true hp.

 

So the car made 435.85rwhp and 402.94rwtrq. Now i just have to get used to driving it lol. Im gonna be installing my air/fuel gauge and motor and trans mounts soon. Just need to try and fix the issue with the active handling needing to warm up and then saying i need to service it. Gonna disconnect the rack and see what happens. I know i accidently moved the steering wheel but i didnt move it very much. Gonna see if the scan tool i have at work will tell me the position of the steering angle

 

Nice going, you have a badazz ride.

 

I see u said that a while ago thank u. It is fun. Had to replace those svo injectors with bosch 42lbs injectors and made another 5rwhp. So now its at 440rwhp and 403rwtrq. Now with the 3.90s the car feels awsome. Looking forward to taking it to the drag strip again.

 

Dyno graph 328 to 435. This is with the crappy svo 42 lb injectors.



This is the 440 dyno graph after the new Bosch 42 lb injectors.

 

Added the corvette creationz wide body fenders. Now just waiting for my wheel spacers from motorsport-tech.

 

How do you like the wide body fenders ? Were there any fitment issues ?

 

Sorry I never got back to you. I love the rear fenders. My body shop guy had to do some work to them to get them to fit better but they look good. Need him to repaint the driver side due to some crows feet in the paint and one spot the bubbles when it gets heated up by the sun but other then that they look good.

 

Damn I wish I had kept my c5Z and still got my c7

Beautiful. My little 383 was trapping 131mph after 25k miles.

Nice

 

Well sounds like something is coming apart in my rebuilt torque tube. I started pulling it apart yesterday. Gonna pull headers and have a friend weld in a bung for my aif fuel gauge and then look at my passenger header looks like a small Crack causing a very small exhaust leak. If the coupling or what not are coming apart then I'm getting the 1 piece dss coupler less driveshaft.

 

Find anything on the TT broken?

 

I have not yet. I just have to finish lowering the driveline pull the driveline and the pull the tt apart.

 

I rebuilt my TT when I had it apart. They are pretty beefy and mine really didn't need it even after 10 years of drag racing. I replaced all the rubber anyway.
Post up when you find the issue.

Pitt

 

I need to do my TT too Bob.
When will you be flying to Portland to do it for me?
😊
