13.5@105MPH

That’s great. Way to encourage someone. Just so you know, I used to own an Integra type R, and when I put slicks on it, i ran 12.0 seconds flat. Stock. All I had was a VAFC to adjust my VTEC.[/quote]

1/10.

The top dawgs rip 1.3x 60 foots - that is face stretching and only achievable by full drag setups

Weekend warriors can cut 1.6x 60 foots. This can be done on nothing more than a decent drag radial. I myself will be getting Mickey Thompson ET Street Radials.

Naturals can cut 1.9x 60 foots on decent tires with stock suspension.

Losers like me an you cut 2.2x

Remeber, as a general rule in drag racing…any 0.1 you cut from your 60’ time will result in a 0.2 second cut from your ET.

Theoretically then, assume you get some decent drag radials and cut at 1.8 60" time… you car could quite possibly run a 12.7-12.9 pass.

But - easier said than done.

Eaaaaaasy 12.7 :slight_smile:

Guess I need to find some drag radials and rims to mount them on :slight_smile:

I just confirmed that MWPD can get MT Streets fyi :slight_smile:

Need minimum 15x7, I think they only go as narrow as 235

Going firmer in the rear is only going to make your wheelhop worse.

Throw in a set of stock 240 rears, set your front dampers to full soft and undo your front right strut bar end link. Drop the air pressure to about 22 psi in the rear. Don’t do a burnout on street radials.

A better 60-foot time will help mid track ETs, but with stock 240 gearing, you’re going to need a big step up in power to go much faster. If you launch harder, you’ll run out of power sooner.

I don’t think the T25 will be able to maintain much more than 12 psi. You’ll probably just end up heat soaking everything and getting slower.

Swap in a 3.70 gear set out of a 300ZX. It will help you 60-foot and MPH.

how come everyone in the world says solid subframe inserts help wheel hop except you? :slight_smile:

Not arguing, I have no idea. I’m just curious.

^^^^^

Because they’re not looking at the bigger picture.

If his entire suspension has been upgraded, he has massive slicks, and enough power to use them, then he might get wheel hop from chassis flex.

The wheel hop he is getting is because the car can’t squat. He’s hitting the tires way too hard, and the car is literally trying to jump forward.

It’s the downfall of IRS. And since Hurricane is likely not trying to build an all-out drag car, (swapping in a 9", mono leafs and staggered shocks), subframe collars alone are only going to make him hit the tires that much harder. Unless he goes to big 15x10 or 15x12 rims in the rear (no 17s, sidewalls are too stiff) he won’t get enough tire under the car to stick it.

He should go the other direction, and introduce more squat to the IRS. This lessens the shock to the tires, and traction demands are much lower. What you lose to the suspension is worth what you gain in 60-foot.

But again, with 4.10 gears, you’re trying to get the car to pull in a 1:1 gear for a good portion of the track. With 220hp to the wheels, it’s not going to cut it.

The better launch he gets, the sooner he’ll be into 4th gear.

I hear ya, makes sense I guess.

stock rear suspension might be worth a try but at the same time the suspension he has on there now is aftermarket but with dapening all the way down, very comfortable (its not full coilovers, spring/struts) and I’m not sure it is a lot different than stock.

Another thing is that he was running 33 or so psi I believe… whatever he runs on the street normally.

On regular street/summer tires on 15" wheels what is a good psi to run?

My first time at the track this summer - I ran about 20psi - but had no noticeable diff in 60’ over 32psi

Most guys on MT ET Streets run 12-18psi in them depending on track conditions

Also from 240 drag guys i’ve talked to unless you are going all out with drag suspension, stock is the best for launching.

As mr200 said, you want to be able to squat as much as you can.

Jammin,

It wont hurt his times, but heating the air can cause detonation obviously, and the other side effect is that he might destroy his turbo.

Both valid reasons to not run more the 12…

i didnt say anything about running more than 12…

you made it sound like more power doesnt necessarily make you go faster in drag

Does Dustin have an A/F gauge?

I’m not sure if he got in yet or not or if it’s hooked up to his datalogit.

Would be intersting to see what kind of numbers he was getting.

he has a gauge installed and everything but no wideband… hence no tuning yet ;(

No what I was saying is, running more then 12 psi on a t25 doesn’t nescessarily make you go faster…

Very different :slight_smile:

definitely just a case of bad interpretation on my part. :smiley:

my bad

It’s all good

Did you run 20 psi on 17s?

Turbo 5 spd IRS cars are about the trickiest thing out there to launch effectively.

Really mushy rear suspension can do wonders. Lowering springs with the dampers set to soft is probably a worse combination. The “soft” setting usually promotes more oscillation - ie hop. I’m sure you’ve been in a car with someone who against their better judgement installed 8/10 coilovers, but they run them with the dampers on the softest setting. Notice on the highway the car has a constant shimmy and you get a bit nauseous? That’s oscillation. The dampers are too soft to control the spring’s rebound.

Stock rear supesnion into the 9s? Say quoi? Say Ben. Lifting it 40 feet out … 2.0L turbo.
