    Anybody run these at the drag strip? MT SS drag radials on factory 18's

    https://www.summitracing.com/parts/mtt-3484. They're kinda pricey, but was thinking of running them on my factory wheels, when the car's not wearing the 15" radial pros. I see they have the same compound.

    When to upgrade diff. and rear 11-14?

    I'm wondering when auto coyote cars start seeing broken parts at the drag-strip with their stock differentials, and axles. On one hand, the shock to the rear in an auto car is probably next to nothing compared to a stick car, and the S197's all at least had 31 spline stuff from the factory...

    Are boss exhaust cams worth the trouble on boosted motor?

    I just see on Tasca, that you can get the boss exhaust cams for really cheap, (less than 100$ each), probably an error their site...

    Advice to new modders

    We've got alot of people here that have been working on Mustangs for quite some time, and have probably learned alot more along the way than we can imagine. I was just going to share stuff that I feel is important that I've learned over the years, you should too. Never beat on, or go WOT on an...

    Any torco users / believers

    Just wondering, if Torco fuel additive is working as advertised for any of you? I'm more than likely going to be adding better rods, pistons, and valvesprings over the course of the winter in preparation of more boost / power, in hopes to keep it alive for better track times, and still enabling...

    OEM Coyote head gaskets for a build

    Hello everybody. This winter, I have the green-light to spend some money to upgrade my short-block to handle some more boost / horsepower. My build is going to be very simple. Manley rods, Wiseco stock compression pistons, boss 302 valve-springs simply to handle more boost from my current FI...

    Great last race of the year for me!!

    Sadly, it was the last race in our neck of the woods, The DA started off at 8500', and climbed to around 9500' at the end of the day. Here's what the mustang did for numbers. I made 11 passes total Best ET was 7.097 Worst ET was 7.264 Best trap speed was 96.5 Worst trap speed was 94.1 Best 60'...

    S550 60' times auto/manual/boosted/NA

    I hate to delve into this, but what kind of 60' times are you guys getting with these IRS cars with possibly 17"rim / drag radial set-ups? I'm just curious and guessing there's some stock suspension auto cars doing pretty well, and I'm really starting to like these damn cars quite a bit, hahaha!

    When/how did your factory 2 piece drive-line fail?

    Hello all, I'm on the fence of either spending the money on a 2 piece drive-line safety loop, or an expensive aftermarket 1 piece shaft in conjunction with a loop for a 1piece. I'm a stalled auto application that has managed (2) sub 1.6 60' times and usually in the mid-low 1.6's without any...

    replacing resonators with straight pipe

    Hello everyone, I know you can buy aftermarket OTA pipes that are a bit larger in diameter, and do not retain the resonators. I was considering cutting out the resonators and installing straight pipe in their spot, and just use clamps so I can swap them out between racing and road trips. I've...

    Compression for Forced induction Coyote on E85

    Hello folks, I'm always looking at (what to do) in the future for my Coyote powered Mustang to make it quicker, and turning up the boost/power is an obvious bridge I plan on crossing. The most attractive option I've thought about is stepping up to a S550 Motor, as I've heard of them making quite...

    Up-grading fuel system

    Looking for suggestions on either continuing running a new stock replacement fuel pump with Paxton booster, or possibly upgrading. My tuner looked at my datalogs, and he said he thought my fuel pump may be on it's way out, and today on my last pass of the day I threw a lean code on both banks...

    adhering wheel to tire without screws, or bead-locks??

    Although it's also detrimental to straight-line performance, is there any hill-billy methods of getting the tires to grip the rim better for drag-racing. I'm running SVE Dark stars, and MT Radial Pros. MT's site says "not" to use rim screws on radial tires, and I'm not really wanting to do...

    Your choice, stall or centrifugal blower? Of course both is the preferred, but....

    Thought it would be fun to see what your opinions are on the subject. For me in the eighth mile, I think a nice stall would buy me more et than a centrifugal blower. I can't imagine making enough boost to make a difference in the first 100-150 foot with a centri without a stall, and in my...

    So what's the RPM ceiling for an 2011 coyote with oil pump gears and boost??

    From what I've read, the reciprocating assy. and valve-train are good beyond what the ECU can manage, and at what point should a person set their rpm limiter? I'm also running a Paxton, and not a PD blower btw. The reason I'm inquiring about this, is because I do nearly all of my Drag racing...

    Testing Paxton BAP

    My car feels like it is running great, and my track logs appear to be good for fueling, but My tuner says my 3rd gear wot pulls to red-line keep showing the O2's trying to add fuel, even after a test tune adding 15% fuel. He's mentioned the possibility of my fuel pump starting to go south...

    6R80 Lock-up with a centri

    Hello all, just curious how others have their converter locking a wot. At the track my car will sometimes lock-up towards the top of 2nd, and stay locked up through the up-shift into third. Of course the locking up feels great at the top of second, but when it stays locked up into third It...

    Can I sand my tint off of my headlights

    My headlights on my car are tinted and actually look kind of sharp, but they suck for actual illuminating the road at night lol. I was thinking about either trying brighter (more expensive) bulbs, or sanding finer and finer to get the tint off and then maybe re-polishing them. Anybody else have...

    Would 2.73's throw a wrench in a supercharged, stalled 6r80's 60' time

    Another member here was talking about getting 2.73 gears for his Coyote Mustang for 1/2 mile purposes, now it has me thinking about those gears for me in the eighth. Right now the highest I've trapped so far has been 98mph, and I'm still using the stock 3.15's and I'm into third a bit through...

    Another good day at the eighth!!

    The car ran good this past Saturday with runs ranging from 7.093@98MPH to [email protected] , no need to mention the few runs I had in the mid-high sevens because of spin issues, lol. The DA started off at a pretty good 7400' at around 11AM, but didn't pay attention for the rest of the day until...

    Raptor 6.2 O2 sensor used on coyote Mustang

    I've heard from a few people that using a 6.2 Raptor's front O2 sensor on Coyote Mustangs will easily reach most long-tube applications without having to employ a harness extension. I've also heard that simply unfastening the harness from the top of the trans will allow the use of the factory...

    Code P2195 (lean biased bank 1)

    Threw a code 2195, (02 sensor biased stuck lean bank 1). I've read that you shouldn't solder the wires on the 02 sensor. Should I try re-using the existing 02 sensor but reconnect using a crimp connector and shrink wrap over the entire connection, or re-splice in a new 02 sensor using the crimp...

    First outing with the paxton

    Hello everybody, the 1/8th mile track I go to all the time finally opened up yesterday for the first time this year, and my car ran great especially being on the first tune from Mike Rousch. Just for information purposes the track's DA was at a minimum of 8700' even though it was a bit chili...

    has any high hp 6R80 guys geared deep and started in 2nd?

    I know it sounds crazy and insane, but with the super low 4.17 1st gear in the 6R80, and the available power with a "built" Coyote equipped with a power adder, it would seem feasable to start out in 2nd gear, possibly in a race tune file just for the track with low rear differential gearing. A...

    MT ET street radial pros vs et street R's

    Hello all, Just been on the fence about my next set of drag tires for the car in my sig below. I've been told ET street radial pros are the way to go, but know of a few members here that are 60'ing well on the et street R's. I have no problem running either, but if I can safely drive the car 200...
