Who's got fast TII's (1/4 mile)
I'm not asking for timeslips here :)
Who's got a fast TII, what do you have done to it? Who's in the 11's? Anyone in the 10's with a street driven car? Anyone in the 11's on stock ports? What are you using for suspension? Tires? What drivetrain parts have you broken and what should get upgraded first? Lets get a thread started so that people looking to build up the car for the first time can save both time and money by buying the right parts the first time. I'm shooting for 11's this year - low 12's at least - but we'll see- I've got a TD07-25 turbo, greddy VSPL FMIC, 3" exhaust, FD intake manifolds, aftermarket EMS, etc. All this on a stockport S5TII mazda reman - unless I can find a ported jspec. planning on doing some weight reduction but nothing crazy - it's going to stay my daily driver. It looks like I'll be swapping front suspensions every time I go drag racing because on the weekends I'm not at the strip I'll be autocrossing or doing a track day. |
I've hit 11/12's with a TII driveline, clutchnet clutch, solid diff mount, and some 245's on the rear (can't remember the brand), had a greddy fmic, 3" exhaust, microtech, fuel, etc. This was with a ton of weight reduction though on a high compression running a bnr hybrid, pretty much stock suspension otherwise.
My GTUs should be in the 10s I hope, it has a GT42R on the side right now (probably will change to a 35R since I don't need such a large ass slow turbo), again a microtech & greddy, some nitto 275's on the back, AGX/ground control for the springs, with a S5 N/a block with a bridgeport. |
12.2 @114 90 t2
1.8 60ft with drag radials 10 psi Ported 2mm motor exhaust greddy fmic stock ecu afc 720cc sec. injectors New Setup ported (yes ported) 13B Re 3mm upgaded T78 new fuel system w/external pump roll cage microtech with 3 bar ect.....10's in srping hopefully |
I've cut 1.5's and run a lot of low 11's with an entirely stock T2 rear axle and stock suspension. Then again I don't have a rotary.. but it shows how strong the stock rear axle is. I even have a stock differential mount.

I believe Carx7 ran a 12.1 on stock sized T1-S's, btw. Edit, 12.4 on 255 T1-S's. Just found out he sold the car :( |

my car technically should be good for a 10sec pass...

bump! common, where are you people, I know you're out there.
if this was a supra forum i'd have found a million by now lol |
depends if you asked MKIII or MKIV.
|
I think he was talking about Mk IV supras.

i'm gonna try to hit 11's this spring with some slicks. in the summer, my goal is to do well at autocross, but this 1.15 turbine housing is gonna have to go :eek:
|
im gonna try for low 13's...
fuel 1.7 rtek SAFC s4 n/a block with stock manifolds s4 turbo 12-14LBS. n/a drivetrain :( centerforce dual friction stock TMIC converted to FMIC 2 1/2 DP to 3 inch hks |
Ive got a 12.3 on my stock port. 1.8 60 foot on Yoko ES-100s. Mod sheet is pretty long, I have a haltech, and all the goodies!

Most important thing is to stiffen your suspension!!!!!! once you make some TQ 400+
I ran 11.7 with stock suspension car did not squat that much but still was bouncy on shifts re did my setup increased the boost and Now the car is crazy!!!! Squats like a mofo, even in the second gear shift...... starts to rock back and forth when the front comes down from shifts.....have to let off the gas to straighten the car out http://media.putfile.com/MOV02741 vs 10.6 1/4 mile chevy Letting off and then trying to accelerate again to no avail ET Street Tires 60' foot = 1.48 Old setup with old paint Job :D on Drag Radials http://media.putfile.com/old-setup Do not dump the clutch say 6K RPM or higher on DR's I did a real good 2nd gear burn out rev'd the engine to 6K dumped the clutch...car squated and snap! broke the outer shaft on the axle... With the ET streets I dumped the clutch numerous times and had no problems They wringle and spin a bit but go foward The Drag Radials and too hard and do not absorb the "shock" Another probelm I had was with the standard HKS WG I had a 10 PSI spring and with the heat and abuse the spring got soft and I was not making power. I took a break from the car and she has been sitting for like almost 6 months now But I got lots of stuff done now. replaced the wastegate with a 50MM version with a 20 PSI spring got a full KYB AGX and Ground control suspension setup (full stiff setting upfront...# 6 out back added a solid diff mount and chained the diff to the subframe car is as low she can go, but the ET streets still can tuck under the fenders added a 8 point chromoly Cage Let me just say she is Quick as F#@! now feels Much faster then when I ran 11.7 did some test runs tonight on a deserted street on C16 fuel I'm planning on taking her to the track this coming week but last time cost me $100 to tow her home cause of the broken axle so I won't be dumping the clutch, just slipping it off the line Still should pull some 1.6 60's I hope I'm wanting to run low 11's to high 10's well see what happens wish me luck...lol |
what kind of power is your car making kabooski

update
came back from the track eh best run did the slipping clutch mathod= 1.62 60' 1/8 7.24 1/8th MPH = 99.82 and dammit! could not get 4rth gear to go in!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and coasted pass the 1/4 at 99.68 MPH 11.59 1/4 the car next to me ran 11.3@120 and I was passing him on the top of 3rd tried shifting into 4rth and could not..... would of been a nice low 11 high 10 pass for sure Next pass..heres the bad news the wastegate line came off and I overboosted broke something in the motor 12 vac reading compared to 16 before still holds a idle drove it home 20 Miles seems just be a warped RA seal (they warp more then they just break) rebuilds cost me less then $500 so no biggie should be back running in a week or so time to add braided hose's with fittings to the wastgate :D |
overboost fuel cut in the ECU would be good too maybe :)
sounds like what happened to me - idle VAC changed but ran fine otherwise, still holds idle too - the compression numbers told the real story though. I don't have the motor out yet but should shortly. what was the issue with 4th? clutch issue perhaps? |
tried shifting to quick I suspect
got to excited when I was about to pass this bad ass chevelle..hehe My goal is to run 10.8 with this setup before I switch to a new one later this year Oh! My new suspension worked great |
power?

Ya, I believe with a proper(good proper I mean) tune pinning isn't 100% necessary, but I mean, if you're boosting like 30psi on a stock S4 motor that might be a problem. The old rule of thumb was like over 15psi, but that sounds kinda..meh. |
My car has hit 11s with slicks, race gas, and a great driver (previous owner). I believe a 11.5 @ 122.
With my panzy ass driving on pump gas and DRs, I've ran an 12.5@109. Also pulled a 12.6 @ 114 with street tires an 2 more psi than the 12.5. |
