LIttle P1 that could.... Procharged S550

Car seems to actually 60' not bad for stock converter- you maybe be better off doing the fuel system upgrade to e-85 instead of converter like you mentioned previously- is e-85 readily available to you(within reason) seems you do a lot of highway roll racing and this would definitely get you more use for your mod $$. then you could pulley down and really hurt some feelings.

Yes, E85 is a couple miles away right on the onramp to the highway. We'll see, I really liked the idea of the new DW400 single pump upgrade that gives you the higher flow for E85 without needing return setup. But lund hasnt agreed to support that yet.

at first when I switched over I hated it- but rolling up and paying 1.52 a gallon instead of running 2.75 premium mixed 50/50 with leaded 110 @ 7.75 a gallon it changed my mind rather quickly- I didn't notice a drastic difference at first in performance because I was always tuned for constant 100-102 octane. but when the hotter summer temps come it is great peace of mind and running 1/2 mile events it is a no brainer. the smell is way better than gas when your uncatted as well. I only drive mine 3k a year thou and my nearest e-85 is 15miles away- but gives me a excuse to cruise the car.

Yea, If she hits 140 on E85 Id be happy. She 60fts ok, but very sluggish the first few feet as RPMs come up.

 

[DarkMach1]

Soo, theres a bit more in it. Car saw 16.5* of timing in 3rd gear and 15.5* in 4th. Commanded was 17* but had close to 1.5* of knock retard. 1-2 shift is still low but dont care about raising it anymore.

Sorry if I missed it, but OP, what is your 1/8th ET and trap?

not bad for a p1! I went 10.3@140 a few times in my S550 with stock converter, 3.15's and a 2200SL on 11.6psi and e85. Get into the ebrake and you can snap that 60' a little better, time it right and you can see a 1.60-1.63 were my best with the centri and the stock converter. you can ramp timing in really hard with e85 downlow which helps them lurch off the line too

Yea I need one or the other to have a chance to hit 9s. Best now is 1.67 60ft but weather is crap now until fall. I’m leaning towards converter unless Lund decides to support the dW400 on E85. I think she’s got 140mph on E85. I’ll just hold out on going until I get the converter. Can’t say I’ve ever heard of using the ebrake on a RWD car, I have seen it done on a FWD.

Good advice and impressive on the Paxton!

@zhisel. What’s up buddy you want to have a conversation? Please come in....

10.36 @ 136 with 1.67 60ft at S550 weight.....imagine when its at S197 weight.

 

[DarkMach1]

As an update....car now has 18x10 forgestars with MTs on it. They are about 7-8lbs lighter each than the Saleens I ran the PB in. But my buddy with a 2018 wants them to run 18x10s in the back and 18x5s in front so I’ll be buying 17x10 F14s with 305-45-17 MT. That makes the gearing slightly longer. Also car just received a set of rear Baer SS4 drag brakes. Which means we have lowered weight ~50lbs (15lbs from wheels and 34lbs from brakes). Fronts will come in a month or 2.

What DA, what boost? What's your suspension setup? Also, the difference in S197 and S550 weights aren't that drastic. Usually 50-75lbs all things equal.

The other dude's car went 9.90s with 11lbs, stock suspension, trans, etc. And that was before the ice box and all the little things that helped him to a 9.29.

Edit: You, an actual racer, of anybody, should know the difference between a 10.36 and a 9.90 is monumental.

My cars PB came on a 60* night, DA somewhere between 0 and +100FT. 10.5psi, stock stage 2 P1sc kit. Suspension is Eibach pro kit springs, BMR cradle lockout and BMR vertical links. My trans is stock, with stock converter.

Incorrect. His 9.9x at 138 came with the VMP, aluminator motor, 69mm pulley and race fuel.

My buddy has a 2014 premium GT auto, with 20” wheels, no spare/jack, Paxton blower, boss manifold. It weighted 3620lbs. My premium 2015 with 20s, no spare/jack, blower was 3835.

 

[DarkMach1]

Here’s the post. Prior to this he went 10.31 at 133 with 1.5 60ft with stock motor, VMP, 75mm pulley, cat deletes, and C12 race fuel. That’s his most equivalent run to me. But you know, I guess centris need stalls to match PDs....

I find that hard to believe seeing as how every curb weight being reported for a '14 GT Premium starts at two pounds less than your buddy's, who has a blower and 20" wheels added. '15-17 GT Premiums weigh a minimum of 3,705lbs from what I can find, so I totally believe your 3,835. But weight aside...

The key here is DA. Any blower car will absolutely shine at your DA, but I haven't seen a post yet from the other dude where he's been less than like 1,000'.

Your car is getting it done though, so congrats man. I drive a lowly nitrous car anyway, so don't mind me.

 

[DarkMach1]

I do see a little bit of a difference with DA. But I mainly like cooler temps because car cools down faster. I can make a pass after about 30 minutes compared to 2hrs.

DA makes a big difference unfortunately, but yeah. A car that can run 8.99 in 5000' isn't a car you'd want to pick a fight with. Haha

1) I never troll posted to begin with, and...

2) I was simply making an observation of how important DA is.

Your original call out for me was to prove a centri could get it done just like a PD car. While there may be one or two freaks out there, nobody is doing it with a 100% stock chassis and at the same DA, which you proved. Carry on though.
