So i have made a few trips to the track now and it feels like i'm hitting a wall at the 10.0 et. and thought i would share my times. I feel like the car could do 9.9 with the right conditions its just so many variables.
Mods on car.
TSP 383
PRC 2.5 heads
MTI cam 233/239 .600/.600
A&A Ysi kit 3.0 and 10% overdrive
RKT built tr60606 and c6z diff
on 93pump and 50/50 meth
Tire is 28/10/17 hoosier and around 730ish whp on this run. This is not a max effort on the setup yet so good to know i can likely get to mid 9s with this.
It was on E85. You definitely have room to grow considering you're barely even at maxed out Si-trim power level. The 28" tire is probably taking a little off the 60' too even though it looks like you cut a pretty good time with it. I'd be interested to see what just swapping to a 26" bias ply would do.

looks like that car is running a 28/11.5/16 i don't think i can fit a 16" rim on the back, i already swapped back to stock breaks on the rear to fit the 17s and its a tight fit.

A 16" wheel will clear stock rear C5 brakes. Some people say minor grinding, some say none needed at all. Hoosier makes a 26x9.5/16 QTP bias ply. I believe M&H just came out with an 8.5" wide 26" tire for 17s too

Your speed is enough for a 9 second pass.

You are slightly overspinning on the launch. (I do like that the nose stays up and you do not bog.) Your setup is capable of a low 1.4. This is where you will get that single digit pass.

This is my buddy Andrew. Great setup that is well driven.

I agree that they will work. We have done this on numerous C5 and C6 setups; however, some massaging of the ball joint and control arm is necessary. The 16 " wheel is better than the 17" but not necessary.
Car looks good, you have the power for a 9 as is for sure. I know the 15" conversion is extremely expensive but it looks like you'r ready for it IMO. That 60' needs to come down, adding power will only take you so far. Maybe look into a set of viking double adjustables as well. I've seen a few c5/c6 set ups floating around for sale out there.

No need for him to spend the money on a 15" setup.
Expensive and always requires some sort of modification.
A 17" will work; however, a 16" works even better.
For the 16", just need to touch up the ball joint and control arm and you are good to go.

You are framing you opinion as facts. Look at all the fast C5 and C6 cars out there, they're all on a 15" set up. By your own logic and as you outline, going down in wheel diameter is better. If a 17" set up can work, provide him more input on how to make it work. Agree a 16" set up is better, my suggestion for a 15" is even better yet.
We have no idea what his budget or goals are. As I outline you can find used 15" conversions for reasonable costs now days. I've even seen them paired with Viking double adjustable coil overs as well. Agree with your sentiment that he can try out a 16" set up but saying outright there is no need to spend the money on a 15" simply can't be stated without knowing his budget and goals. If he has the money and is looking to go faster, spending money on that would be a solid investment. You also talk of "requiring some sort of modification" like it's a hassle, or something to be avoided. Dude we're on a enthusiast website talking about drag racing highly modified cars. It should be a given. Plus you acknowledge you need to grind and modify even for a 16" set up. Not sure why you appear to have taken such an exception to what I outlined that you literally replied just to refute my suggestions.

So a small update is this got delayed. The day before swapping to e85 and upping the boost I had a lifter failure. It’s almost back together now just waiting on a new clutch while I have the motor out. I was considering doing the 15” conversion but the clutch was not looking so awesome so that takes precedence.

Sorry you took my quick short comments as an offense.
I totally agree with you that a 15" setup is better. (More tire choices, more sidewall, easier on parts)
However, I am stating facts; not an opinion.
This is based on personal experience as well as analyzing the OP's timeslip.
A mid 1.4 sixty can make his goal of a 9 second pass achievable.
The 16" tire setup is cheaper and less labor intensive than the aforementioned 15" setup.
It will produce sixties in the 1.3 to 1.4 range regularly.
As for looking at the fast C5 and C6 stick cars out there, I believe I know a few.
Again, I meant no disparaging remarks to your opinion.

A 15" setup can make it easier but again not absolutely necessary.
Sorry to hear about the lifter.
Just wondering, how's the cam look after that?
Good luck on your quest.
Keep us posted.

the cam on just that tip was a little jacked up. Went with a tsp cam this time. Thank you.
Trying to get a 9 sec pass
