Those times are very good, more then I expected to see from stock tires. If that had some slicks on it it would have been low 12's
Impressive.

 

They make no mention of adding rear tires to the equation. In their video, it appears the car is running larger tires than stock on the rear.
Anybody else's opinion? Larger tires or stock?

 

They say they are stock, there no reason to believe that they arent. Trying to tell just by looking at the tires is tuff. You could go both ways. They are not slicks though.

 

If they say they are stock, I will believe it. I am sure the car is easily good for low 12's, just like to know exactly where their times came from.

 

It doesn't say they are stock tires it says they are street tires and therefore could be wider or stickier than stock.

I hate it when an advertiser omits pertinant facts. :notnice: Makes for info that is worthless.

 

Very impressed! Mid-12's on stock tires with only a gears, pulleys, intake and tune. Very, very nice. :worship:

 

It was not stock tires. It was wearing 17" ET streets. JMS freely admitted this on corral net.

Look for post with the timeslip attached, still very impressive !!

Thanks for clarifying!

 

Not too bad of a price for the packages. I may be looking into the one with the pullies, tuner and intake.

 

Can someone explain what the charge motion plate does???

 

It DELETES the factory charge-motion valves, which are used to change the geometry (runner length) of the intake mani depending on engine speed. I guess Steeda has found that they're restrictive on the top end.

Yeah, the "street tires" thing is a bit lame but hey, the thing still traps 107 with a filter/maf housing, pullies and a re-flash. Oh, and those charge-motion delete spacers.......assuming they do anything.

 

That has got to be one of the biggest bangs for your buck when it comes to performance. Keep in mind the parts are $1000 that dosen't include installation.

 

Pretty impressive......I thought we were getting 26rwhp with the MMR/Steeda CAI and SCTXcalibrator w/o adding pullys? I had read a bit about the "Charge Plates" and was wondering what they were for. I did see them for sale individually - IIRC it was Steeda?

 

JMS did mine SCT tune! Steve and Monty, great guys!

 

I think that this proves that gears do a majority of the performance by numbers at the track. We all have seen cars with tunes/intakes that make 26rwhp increase and know that most 1/4mi times have been in the low 13's. Others have changed only gears to 4.10 and been in the low 13's. Looks like 4.30's and some tires with a decent bite at the track are the perfect combo.

 

Good point. Seems like the 4.30's would let you wind out 4th gear better than the 4.10's.

Also, as pointed out by others, 4.30's in the '05 are just about equivalent to 4.10's in the previous model years, which was the optimal ratio for street/track use.

 

If the car's not seeing daily street use, go 4.56s

 

That thing is movin!
