Testing coming soon.

I posted this plate frame on my personal page and i had alot of interest in them. They are 3d printed out of ASA, no problems holding up for a long time.

If your interested, i was thinking about making a few for 25$ (plus shipping). Just enough for material and machine upkeep.

If you PAID for a shirt from me, please reach out to my personal facebook (kyle larkin) so i can ship them to you. I figured most people if run into/have appointments with, but it just did not work out that way and id like to get your shirt to you!

Thank you for your continued support!

ATTENTION ALL CURRENT/FUTURE CUSTOMERS

Especially those working with me remotely.

Please do not send money to anyone claiming to be me, via text or any other means. I will only talk with customers via this page, my personal page (https://www.facebook.com/kyleiscoolmane/) and my email [email protected].

All payments will be handled through an invoice (as they have the last year or so) and Apple cash is not one of my methods of collecting payment.

Please let me know if you suspect someone is trying to impersonate me, or use my likeness to collect money for services not provided.

Time has FINALLY come to try out the Lurk Tuning OBD1 VR6 x Haltech S3 PNP adapter.

The VR6 is a great, under appreciated and cost effective engine. We have made upwards of 600Whp with a factory rotating assembly with these engines, and this unit is being paired with an engine with goals much higher.

These will be available for pre order soon, with development also in the works for OBD2 chassis and B5 swap platform.

Long time, little posts!

However we have been busier than ever with tuning, wire and just building cool stuff!

I do have a limited run of T-shirts for sale !

LARGE sold out

XL SOLD OUT

Shirts are true to size with minimal shrinkage, and 100% of proceeds are going towards a much larger order of shirts, hoodies and stickers!

25$ , leave what size you want and i will send you a dm with payment info!

As promised some product development underway...

All the pieces of the puzzle have arrived for PNP solutions for both obd1 and obd2 VR6 platforms. Myself being unsatisfied with the current accessible PNP solutions, figured we would make it easy for people to use one of the best consumer level ecu's on the market.

More to come once this is all together!

Tis the season of the rampant post about ethanol content.

while I actually went as far as researching this topic in depth and recording a video, during the end phase of that I stumbled across a video that perfectly summarized what I was going to say anyways.

While I will link that video and some research papers, I figured id go over a few important details that those of you whole just want to scroll and not watch a video, can benefit from.

Ethanol (e100) is less energy dense and scale's linearly, that is why various ethanol blends require various additional fuel volume to reach the same burn energy.

𝗢𝗰𝘁𝗮𝗻𝗲 𝗿𝗮𝘁𝗶𝗻𝗴 (Chemical advantage)

Ethanol has a NON-liner increase in octane rating, e50 when blended with CARBOB (87 octane) you have around the highest octane at around 103. after e50, you have very little notable increase in octane.

𝐋𝐚𝐭𝐞𝐧𝐭 𝐡𝐞𝐚𝐭 𝐨𝐟 𝐯𝐚𝐩𝐨𝐫𝐢𝐳𝐚𝐭𝐢𝐨𝐧 (thermal advantage)

Ethanol (e100) has a higher LHOV than gasoline. this scales linearly with different blends. LHOV refers to the heat (energy) used in phase change from a liquid to a gas. this is why ethanol blends commonly are associated with "cooling properties". This property also becomes more prevalent when you factory in the additional fuel volume needed for the correct burn, so with higher e content you have even more "cooling" as you are injecting more fuel with a higher LHOV. lower in cylinder temps, reduce the possibility for a knock event to occur.

𝐜𝐨𝐧𝐜𝐥𝐮𝐬𝐢𝐨𝐧 (opinionated but based on science)

If you have an engine that can operate with just the added benefits of higher octane, e50 or higher would be perfectly adequate and suitable. there *could* be some additional power on higher blends due to some other properties of ethanol like frame front propagation in regards to cylinder pressure as well as the oxygen intensity.

If you have an engine on the raged edge of these general octane ratings and/or a scenario where you have less than desirable charge air temps, it would be best to go after the highest ethanol content from a 𝐬𝐚𝐟𝐞𝐭𝐲 perspective.

Note that LHOV increase is even more advantageous with DI engines VS PI engines.

Let the comment frenzy and arguments begin!

more science related posts to come, as well as developments ive made in regards to motorsports wiring and product solutions. I know I have been pretty quiet on here, but i promise you that is not from a lack of effort, alot of things going on in the background, and alot of very good things to come.

Did a pretty poor job posting last year, maybe this year will be different!

Pretty happy with this one, not a 300zx or vg30 guy by any means, but it sounds great and made great power.

725whp and 725tq

We installed a haltech nexus S3 with the haltech PNP adapter, as well as a customer mount (design and made by LTD) to put it in the factory location!

Overall great weekend up at Brainerd International Raceway for round 2 of North star speed summit. Had a few customers do very well on the drag racing side!

Xue from team shadows taking his car into the 9's, resetting his PB twice this weekend! Need to work on getting the car to leave, but overall a solid weekend and the car didnt skip a beat!

Brett Anthony going 10.4 on a 205 hard tire after a few changes last year, resetting his pb! This car has way more in it, and will definitely pickup some time when we get some slicks on it!

Cole Peterson making some hits going 11.3 with his street car! Mph says its got way more in it!

Lucky Uchiha going 12.5 with his all motor street car!

Collected some great data and had a blast doing track side support 💪🏻

Last minute call to action!

Any and all sport compacts looking for alot of seat time, and potential bragging rights, North Star Speed Summit is place to be.

With the same classes (and rules) as the spring event, there should be very little suprises. If you do not currently fit in one of the designated classes (outlaw, pro and sport) then the index classes are a surefire way to get some passes in for the end of the year!

I will be out at this event collecting feedback from racers and spectators, as well as servicing any of my customers who may be on track. Look forward to seeing you all there.

Phongs beautiful lotus back on the rollers after refreshing the engine and adding a large set of cams!

Picked up 15whp with just the cam change, however it seems the un-ported OEM style intake manifold is holding it back! Plenty of power to keep this thing fun in the turns

We are on our way up to Brainerd International Raceway for the Northstar Speed Summit event this weekend! If you are in need of tuning/log revisions give us a message or visit the JWP booth.
