A friend overlaid one of his laps from mid ohio with my lap from last weekend. It wasnt my fastest lap but was one of the cleaner videos. https://www.youtube.com/watch?v=cERupOm1IHc

I am getting pretty desperate at this point. I am looking for the terminals that go into the 16 pin ECU connector for the knock sensors. To my knowledge there are only two terminals used for the ECU connectors one large and one small. This is for a 89+ harness. I found these part numbers...

Well I have hit a road block so I need some help. Last year I had some issues with the brakes dragging and then the fronts in particular locking up after racing for a certain period of time. We were able to isolate the problem to the master cylinder because when I came to a stop with the...

I was able to borrow a friends camera which enabled me to actually take some video for once in about 5 years. Here is a link to my new personal best at mid o a 1:39.1 confirmed via amb transponder. This was on the lastish event of the year (on fence about putnam). I should with a fresh...

I "think" I may be having some breakup at high rpm (5750)+ in my race car. Engine is essentially stock with 10 psi of boost. Ill be heading to a dyno this offseason to do some tuning with the SAFC2 I have (not installed yet) to try to get the air fuel ratios under control. My main question is...

I race in nasa time trials. As such there is a point for mod system which I need to use the best to my ability to be/stay competitive. One area I believe I can gain some points back from is the fuel pump points. There is a modification listed that gives me 2 point if I run an non-OEM fuel...

This is posted as a sticky in the vehicle dynamics section, but since this forum gets higher traffic I think this is the best placed for peer reviewing this tool. Attached is an Excel 2003 sheet that determines based on an user inputed torque curve, tranmission ratios, and rear end ratio what...

This excel sheet was created by me and my friends to allow for the proper determination of shift points. I will be posting a report of how the calculations are made in the coming days. In order to use the sheet you must input your torque curve. You have 15 cells to use you can use some or all...

Here is a file from TIP engineering with some common bars and their respective stiffness values. I will be making a more detailed post on how to use these numbers and what they mean shortly.

This is just a thread to document some of the changes I am making to my car for the winter to get it classed and to fix some reliability issues and most importantly get the weight down. there is going to be a ton of pictures most without descriptions so if you need something clarified just ask...

I am building a turbo engine for a friend and the check valve is missing out of the turbo manifold I have. most likely I took it a long time ago for the race car. My question is how important is this check valve for a engine that is just going to be on stock boost. I assume its there to...

Just took the car out for some fun. i didn one or two serious runs then the rest i was just trying to lay as much rubber down as possible. won my class against 6 people. the car is on 275 azenis which still isnt enough grip for even stock boost. http://www.youtube.com/watch?v=6UhCYIE2azM...

I just out testing the car before the putnam race this weekend. for those of you wondering this is just stock boost with no gas in the car and a rear sway bar up on full stiff. this is obviously not how i usually run. for autocross on street tires i recommend 3/4 tank with the sway bar on...

This might seem like a basic question however there is some pretty sad stuff going on here. alright i have a pretty serious track mk3. it has dual oil coolers running in parallel with a remote spin on filter and a thermostat. i have a rebuilt engine with a new toyota oil pump shimmed. with...

PLEASE I beg you email this person with a quick email saying how poor the brake pad market is for our cars and how you would love to have the full line of hawk pads available. detail how hard you drive your car etc. tmiller@hawkperformance.com we really need to make this happen, i have...

Might seem random to some, but I need a clear way to determine whether a camshaft outside of the head is a turbo or NA camshaft by the naked eye. I have infront of me two camshafts. One I can guarantee is a NA cam and the other a unknown cam. The only numbers I can find on the camshafts is on...
