A few runs against my sons c7.

[Unas2k5]

You’re gonna need a re-match. I’m only making 618WHP on my large 93 pulley and I DESTROY the new C8s. You could’ve done a lot better lol at least he’s your son I would love to race my dad !!! Have fun!

Yeah. Gonna be a rematch.
but hopefully after better tires and some dyno time to rule out a power loss.

If you can’t put power down by 3rd gear you surely need better tires and/or a wing.

Yeah. I think something is going on with the car. I don't get any kr at wot. I run 91 octane with 4oz boostane professional per tank. Seems to run fine. New plugs, coils. Injectors were professionally cleaned. Great compression and leakdown test was great. I'm kinda at a loss. I dd drive the car 80mi. Round-trip on average 3 to 4 times a week. I'm here by kc. And get caught in the rain sometimes. So would like a tire that wears alittle more slowly and can handle rain and some cold. I didn't buy the g2s that are on there. The prev owner just put them on right before i bought the car.

How much boost is it making? Do you have a reliable gauge? I say reliable, because some of the offerings are shit and off by 2-3 psi or more.

 

[furdfan2018]

One other thing I can think of is I always leave the car in normal mode never use sport mode and I leave traction control on, could that be reducing my timing maybe?

lol, yes. Bigly. Especially on shifts you are losing power.

Turn all the nannies off

I can't with these 373s. Would prob already be around 6krpms plus it will blow the tires off. I have 305 nitto g2 on the rear. But It would just kick the car out if I punched it in 3rd.

Nice runs. Those vettes are no joke.

3.73 and a 26"? tire gets you to a top speed of about 90mph. You should be able to start in 3rd if you aren't traction limited. I'm guessing you have a PD blower?

 

[Lonniesgt]

Just using digital boost gauge that you can add with forscan. So it's inferred. Should be around 10psi with the longtubes. It's a pd blower whipple gen 5 stage 2. 3Liter.

I do need to get a better boost gauge

I agree. With a blown mustang like yours, you would do better with 355s

 

[Lonniesgt]

I was kinda thinking 331 gears. I do alot of highway driving.

I am sure it’s been said already but get those G2s off lol. Those things have to be comically bad with 710HP. Also 3rd gear all day.

Maybe I am misremembering my 2015 manual with 3.73s but I know my 2019 6 speed with 3.73s takes 3rd gear up to 116ish mph.

Ratios changed in 2018 (4th gear is off a hair in the chart but whatever)

 

[ShadesOfBloo]

I'll have to try it. But traction is another thing. I never had 3rd gear hold without back peddling. I think these nitto g2s suck balls.

What kind of tire does he have? Maybe that's what kind you need.

I'm gonna have to check.

If you insist on no DR's at least look at some R888R's or something along those lines.

Are the R888R's much better than the ps4's?
