Type S at track
went to the local test and tune 1/8th mile this weekend and figured I'd share runs from the gopro. ran into couple of turbo mazdas plus a mitsubishi evo 8.
first run was against mazda speed6 with intake/intercooler/e85 tuned ecu… talk about sleeper. judging by looks, you would think he was stock besides the intake. by far the quickest mazda I have ever encountered. his fastest time was 8.4x@85mph (that night supercharged gt was running low 8’s@90mph)

also got to run another speed6 without ecu. accidentally fouled off the line but we were neck and neck almost all race, then I pull after he misses gear. he runs 9.07 but somehow I won with 9.27

had a hard time launching the auto but its easier using sport shift with vsa off. wish I would've bought the quicker 6mt lsd. ran decent times considering bottlenecking stock exhaust. I was running oem michelin pilots 20 front 30 rear psi around 70 degrees out. best run of the day was the first. I'm guessing because of track temperature rising? my trap speeds was consistently 77-78mph. fastest time for this season was 9.23 1/8th against the grey speed6. overall met some friendly people and got good idea where I'm at with current mods

Not bad. What are your exact mods? And what were your 60'?

^ Yea true, 9.23 isn't bad though. My best is 9.13 on a 14.0 run. Gotta get into the 8s.

thanks sonnick. seen videos of ur accord and very impressed with your times. you really know how to shift that j32, should be breaking 14s with just couple mods. i'm hoping similar results
k&n short ram, p2r tbs with 2 thermal gaskets, tb coolant delete, maxbore tb bore+new butterfly, port n polish mani+runners done by gerzand, stock dual exhaust. minor weight reductions. will have the rv6 true duals when richie starts shipping them out.
My 60' was 2.2312 on that 9.23 run. Fastest 60' was 2.1950 on different timeslip.
agree they are short and pointless. I barley hit 3rd but regardless I got baseline times and trap speeds I needed. also good practice launching the car and finding proper psi for the tires. called "test and tune" for a reason...

and the tree isn't that bad once you get a routine. i avoid the burnout pit and stage slowly. i always run low tank with few gallons of e85 mixed with 93. some people just roll up and stage both lights almost immediately. but if u watch the outlaw cars they barley set off the 2nd stage light. this is so your tires will be further away from the sensor that computes your launch. therefore lower 60ft times which helps your times throughout the whole race.
i don't know much about launching the 6mt but i can tell you i always gun it before the last green light and that seems to work pretty well. had .068 reaction on my last run of the night. its all about how in sync the driver is with the car.

it definitely takes more practice launching but once you get couple runs its not that bad. never drove manual tl but i could only imagine the torque on the throttle in low gears. dont worry about reaction bc u can sit at the tree all night long and ur time doesnt start until you get on the gas.
you do the slave cylinder mod?

dyno pulls
hooked the tl up on the mustang dyno today just looking for some baseline hp/tq before added exhaust down the road. no air/fuel this time. you can obviously tell by the graph droping tq off how bad stock exhaust is restricting the flow. so he was cutting the graph early before i got to 6700rpm. not really sure what to think of the results. best numbers with correction factor were 251hp 243tq. 2 guys in the videos told me multiply by .15-20% then add to get apprx crank hp/tq. so i hope i'm approaching the 286hp sticker rating. let me know what you guys think.

those numbers seem about right for your mods....once you get that Rv6 exhaust it should get you closer to 270ish...nice runs btw and 2.1 60' not bad at all...

^ It's not in your trans. You should be fine as long as they left the slave cylinder alone.
OP: That torque curve is really odd. I know we lose torque towards redline, but it doesn't drop off that drastically. Next time you go to the track try unbolting the exhaust from the Jpipe and see if it's any better You need the cat deletes as well, that's most of your bottleneck considering you have a ported TB/manifold/runners.

?- did you notice dead spots in 3rd gear around 5k before you got exhaust.. how was the powerband after exhaust
it was a 2.195 so might as well say 2.2 flat and call it a day lol. that was my personal best 9.163@78.02mph. that low 60ft helped me everywhere
thanks i'm happy with the results. so difficult choosing between mustang or dynojet. went mustang bc they can run simulated quarter miles. i figured the 6mt base and 5at tl-s are in the same league after similar bolt ons. the sc mod and power shifting will help ur times throughout the whole race if u can get around to it again. hope you run low 14's friday

i'm glad someone noticed that tq. when i saw the graph after my first pull i was . thought to myself that can't be right no way my tq falls off the charts shortly after vtec had kicked in. i immediately started naming off possible problems. i knew my exhaust was holding me wayy back, nothing i could do. then i got nervous trying to recall if i torqued all the bolts to my runners correctly. do you think its possible that my runners/manifold could be leaking? we checked for any unusual sounds but no luck. so that made me think that its a combination of the resistance they use on mustang dynos and the fact he was cutting me short at 6200k rpm which could explain why it dives as dramatically it does. but i know very little about dynos...

Yea it could be because it's an auto trans? I'm not really sure.
Justin, I think you're right considering yes, it's connected to the trans. I'm not sure if they would replace that as well though, they may have just disconnected it and attached it to the new trans?

why cut you off at 6200k? that could play a problem to why it drops off so badly? idk though just thinking out loud. as far as falling off I didn't feel it, maybe cuz I removed mid-muffler and resonator from stock exhaust right after I bought the car( I did have some dead spots but can't remember where maybe it was same as yours)....Also once I put the RV6 TD exhaust it did shine in upper mid range and top end. Then with tune it really came alive. I don't have the TB bore. or manifold/runners ported like you so when I dyno'd before getting the tune with full Rv6 exhaust I netted 260whp on dynojet. So your numbers are strong numbers. So after you get RV6 TD you should be 270-275 since you have intake side mods, with JnR tune you'd be over 300whp pretty sure!

the dead spots aren't that bad but definitely audible in the videos. once i got close to 6k the needle would stall then very slowly advance. it was the first time the problem was really evident to me. on the street, noticed dead spots in 4th of course but not so many in 3rd.
as the days count, i get more and more anxious for this exhaust. feel as if youtube videos distort sound of the true dual, its one of those things u gotta hear in person. boston u got a great setup man. i bet driving that car is a blast with such a smooth power band. i really need engine management so i can get the most out of these cars. definitely made the right decision by having rodney tune your car. if something goes wrong hopefully it wouldn't be on your end and would be fixable over the phone or by rodney himself. if he works out this group buy and other issues, with good service and more satisfied tuned customers. then it'd be safe to say, i'd be placing ecu, knock, injector order in the future.

Mustang dyno's will crush your hopes and dreams....also sometimes even when you are not making peak power at redline it's better to rev it out because of where you land in the powerband for the next gear...if you are constantly shift at peak power you might fall out of the powerband or hit a "dead spot"...

don't know about you, but the weather this weekend was unbearable. when is the next date for test and tune?

OP: I'm not saying this is the case, but some Mustang dyno's can be calibrated to read identically to a Dynojet. In this case, I'm not so sure. Your car seems to be running strong though and that's all that counts!
And x2 on taking it to redline on the dyno no matter what. No reason to stop it. You want to see where your power peaks and how it 'holds' to redline. You could peak at 6200, but be within 5whp at redline and you wouldn't know. Get an exhaust

i think if you get the PCD's and Exhaust (considering you have Jpipe) you will see ~28-30 HP....more than 2/3's of that coz of the PCD's....
Other than that.....great videos and awesome Dyno session....keep up the good work....

^ don't doubt because I was at 260 and I don't have the intake TB and PnP that he has so 270 is very possible, If I netted 260ish with Full RV6 Exhaust, but I am saying this with PCD and Jpipe included so maybe thats where we misunderstood!

^^^ aaah yes...right there....
the base gains 20+HP from the PCD's as out stock cats are pretty restrictive....hence the Type S gains a little less from the PCD's and Jpipe combo as your stock cats are pretty well flowing....

my next pulls will be with exhaust and lightweight pulley... awaiting your results with the 3.7 mani+tb work
i'm hoping to put down more than 260 with exhaust. my mods have added about 17hp with stock exhaust. assuming that auto type s dynos 234hp out of the box, I think 270+ is very possible after couple mods
#39
i'm guessing u raced near stock evo. my buddy basically has an EVO X minus some goodies in the ralliart. i would be down for some friendly pulls if you didn't live so far north. you ever travel in the cincinnati area let me know

^ I didn't mean to imply your numbers are high. All I meant by that post was that you can get Dynojet numbers out of a Mustang. Only reason I dyno'd on a Dynojet again was because it was the same shop owner and I wanted to compare to my previous numbers. I'd rather do pulls on a Mustang (and will at some point) and use those numbers for a surprise party
