To Dyno, Or Not To Dyno...

[DFG 5OH]

Well I'm sure some of you remember what happened the last time I tried to dyno, my car wasn't running right, and I blew out a tire at 150mph...
View attachment 499860

Anyways, I've got another oppertunity now that my car is running right, to re-dyno, at the same place $35 for 3 pulls with wideband. I've got 4 16" waffle wheels on my car, with 4 215/55/16 Toyo Proxes 800 tires. I know they arent Z rated, so should I dyno again, or wait till I get new tires? I'm just really nervous from last time, and this time I dont have the money to get new tires...The Toyo tires are nearly new...

What should I do?

haha, if i did blow a tire again, which i think would be un likely, i would be out a car for a while...

 

[Suspect]

you can do it!! i have those same 17" gt wheels with good tires on em id let u hold, but i think u live a bit far. seriously good luck!!

 

[DFG 5OH]

but do you guys think they'd blow out, or was it just a freak thing? its not until nov. 12th...but i need to get an idea of what to do.

Buy one new tire for the 99+ wheels, and run again with those. FWIW, i was crazy enough once to bury the speedometer in my old Fox (140 speedo), on only H rated tires. You'd be substantially safer doing it while stationary, on a dyno. I say go for it, you gotta put those old numbers behind you

You shouldn't have any issues, Matt. I've maxed out my speedo on Yokohama Avid H4's, not Z rated, and there was no problems at all.

I would do it, just make sure there is enough tire pressure in the tire so it doesn't heat up on you and go for it..

You should be fine man, dyno the beast and let us know how well she does.

For $35 do it! Thast fuggin cheap as hell!! Bring a timing light and play with timing.

 

[DFG 5OH]

well i know its cheap and all, but i really dont wanna risk blowing out a tire...

A 140+ blast is not going to blow a tire, the ratings are for continues speeds a few blast won't hurt.

What was the condition of your tires when you had that blow out? Also, did you have any clearance issues (using wheel spacers or otherwise)?

It seems like that should be a pretty rare thing, but I don't really know. You also could ask the dyno guys how often they have blowouts, and mention your concern. Seems like they should have a pretty good handle on the issue.

My thoughts as well

This is the first and only time I've seen the dyno tire blow out thing.

I wanna see your pull......................GO FOR IT!

With only making 150rwhp the last tune, can you imagine breaking the 160rwhp mark your cars going to grenade

my tire were worn, but werent that bad, i had no spacers ect. The dyno guy said that has never happened...it was really weird.

Sounds like just plain bad luck to me, get your ass back on that dyno. :Teh-Win:
