MazdaSpeed Turbo engine

[miata_racer]

I'll just copy and paste mine. My alignment (if I remember) is about -2.4F (4.5 deg casterF) and -2.2R and 1/8 toe out F and 1/8 toe in rear.

 

engine:

- bone stock motor with 146k miles

- ebay maf adapter to a 2.5" straight shot of exhaust tube into an AEM filter off my mazda3's old intake (with 3" dryer tubing around the 2.5" pipe

- bosal header off someone on CR.net

- jackson racing cat

- magnaflow exhaust (removed muffler and ran with turndown @ rear axle)

- alum underdrive pulley

- 14 deg timing advance and 93 oct fuel

 

 

other:

- removed A/C and most plumbing under hood

- depowered rack

- removed passenger seat, soft top and rear shelf insulation...still got carpet there

- fans wired in synch to run all the time (stock 1.6 replacement radiator)

- alum tape over cardboard for my rad panel :)

- tsi intakes

- 4.1 T1 torsen

- 8lb motobatt battery

- simpson lap belt and foamectomy driver seat

- worthless motorcycle mirrors

- hardtop with rennenmetal mounts

- HD M1 Sport roll bar (hope to have a kirk 6pt later)

- home depot garden edging air dam

 

brakes:

- no prop valve...straight unions

- 1.8 rotors and xp12 pads up front. stock 1.6 and Axxis ULT rears

- the US brake fluid fron safe racer

- 949 SS lines

- cheapass STB with bolt for MC brace

 

 

suspension:

- 99 NB bilsteins revalved by bilstein in Poway, CA Feb 2009 (12k miles ago or so)

- GC coilovers 700/450 rates

- RB 1.125 hollow front bad and mazdaspeed links. no rear bar

- ISC racing top mounts

- 15x9 tire rack wheels with hankook RS3s or the 13x9 keizers with some crap slicks

 

 

 

I think that's about it. with 1/4 tank of fuel, no hardtop and a stock passenger seat (on my 13s) it weighed 2050. So with the 6lb heavier 15s and 15" tires being 5lb heavier...that's 40lbs....plus maybe a 15lb difference in weight between the HT and a pass seat? I'm ad actually 2320 with low fuel...so maybe 2330-2340 most of the day....

 

 

CW lap times - 2.02.0-2.02.3 range

CCW - no idea...I did a 2:01 in a stock 2001 2.7L boxster on old victoracers 6 years ago before the motor popped. I suppose the miata would be close as is?

With the recent change to the front sway the car was significantly less pushy, dare i say neutral. No times yet with the tweaks. I want to try running a little more rear bar and see how drifty it becomes, cause you all know how i like to drive ;D . Basically I've been lazy and have been driving my pre aero setup. adding the aero added some grip, but changed the balance and i'm finally getting off my ass and setting up the car with the aero.

Damn you! I had a 7:44 in the old MS6, course that was on a red flag lap when an uber hyped (450whp) STi flipped on 8 running CW..no fun!

Well for the record, with street tires (Dunlop SP600's) and in a daily driven STi, I did a 2:03....only reason I know as I was on Greg Wallace's azz for a lap in his Cayman S and he had all the data acquisition info that backs it up. I'm still a pussy though, Misty wanted me to instruct because I'm smooth and know the lines, not because I'm the fastest out there :)

1991 Miata

232whp/212wtq

AST 5100

2.8*f/2.6*r camber, 3.5* caster, 1/16" toe-in on rear

225 NT-01's on a 9" wheel

Corrado rotor w/ Wilwood Dynalite and DTC-60's

2300lb car, 185lb driver, 160lb passenger = 2645 (lol)

 

2:00.2 CW (Traqmate) on my first day out there...should have scored a ride-along sooner. Once I had the revelations from riding with Colin I could not get clean for the rest of the session.

 

There are definitely 2 more seconds out there, probably 4. The car is retarded fast, the driver is retarded; this makes for a unique combination of failure.

 

Edit: Updated HP figures after a recent dyno...numbers went way down, lol.

[ffej]

1991 Miata

250whp/240wtq

I'm incredibly jealous of those numbers, but totally unwilling to dump the money into my Bavarian motor to get them.

 

225 NT-01's on a 9" wheel

What is it with you Miata guys stretching too small tires on your wheels? I fit 255s on my 9" wheels

LOL!

 

That you'll admit to it means you're far safer than plenty of people I've had the "pleasure" of screaming at from the right seat.

[hustler]

For the record, although the engine numbers are phenomenal on low boost (310whp at 18psi on a Mustang Dyno) the suspension performance trumps the motor by a country mile. The car is fun with power, with the nice shocks/grip it's unreasonably fast.

What is it with you Miata guys stretching too small tires on your wheels? I fit 255s on my 9" wheels

The Toyo/Nitto carcass is wider than 225mm:

they have a very slight "pull" and that is a world of benefit in terms of feel, pressures, and ultimate grip. I prefer a 205 on an 8" wheel over a 225, and the slight stretch is significantly faster.

 

That you'll admit to it means you're far safer than plenty of people I've had the "pleasure" of screaming at from the right seat.

My lack-luster lap times tell the story...but that story is evolving. There are a few corners that are "no lift" in my car which I do not possess the testicular fortitude to hit at the limit. Track glory takes a back seat to driving the car home. Hallett is the only track where I can boast.

Time trial log from Jul 2010:

Seems like 1:57 is good achievement for TTA/TTB class car.

I don't know much about NASA time trial rule; what would a Miata turbo with race suspension/tires be classified under?

It depends on points, but most likely power/weight will put us in TTA at 240whp+ on a dynojet. Judging from what I've run at Hallett, MSR-C, ECR, and now TWS, that's where I expect to land. Give me a set of Hoosiers and I'll feel a little better about TTA. Ken Ogeron is my nemesis, I should be running a tick faster than him (with his Hoosiers) but I don't have the testicular fortitude yet. The guy is good.

 

Again, those guys are on Hoosiers while us Miata guys typically run R-comps, so TTA sounds about right for my car...now I need a set of expensive rubbers. I feel that with a set of Hoosiers on my car, at a track I know, I'm a protest away from TTS.

most land in ttb. even hustler with his power will be in ttb due to weight and lack of aero points. sixace and i start at ttc +14 points. after wheels,tires,susp.,aero, etc.. we are a few points from the top of ttb.

[learningtoshift]

laptimes without an attached traqmate or g2x date file, or video, or link to race results are "big fish" stories..

 

The fastest I've been in my E90 is 1:58ish (I counted the seconds) - sweet setup:

 

- NT01s

- DTC70s

- SRF

- Normal shock mode, normal throttle, normal steering, all nannies off (thanks but no thanks BMW)

- 210lb passenger (carefully selected to get the corner balance perfect)

- 35lb baby seat behind driver

- "My humps" playing loud enough to hear over cut-outs and a helmet

- some random kids toys rolling around in a place I can't actually find

- shop towel zip-tied over power-steering reservoir

[C.Fuentes]

My best time at TWS has be 2:10 both CCW and CW.

 

Stock 1990 Eagle Talon AWD

stock 14 PSI boost

suspension is upgraded Koni yellows and GC coilovers.

230lbs driver

street tires.

3260lb car with full interior

[Geezer]

CW: 2:00.8

 

MX5

Hoosiers

Coilovers

Approximately 160-170 WHP

2450 lbs/no driver

 

First (and only) day I've ever run TWS CW, and this was after about 40 minutes. Then I corded a tire. Pretty sure the car has a 58 in it.

 

CCW: 2:00.x

BMW M coupe, Bone stock, Direzza Star Specs.

 

Don't have an MX5 time, but I'd guesstimate the car is capable of high 56s/low 57s CCW.

[Spiderxvpbiking]

I agree with Shakenbake.

 

TWS CW and the same for CCW

[JamesL]

Interesting comparing the CCW vs CW times in this thread... I was under the impression CW was ~2s faster than CCW from people I have talked to.

 

Is it simply a case of having more experience running CCW? Or do you guys actually feel the track is faster CCW?
