I picked up a zhp with an ESS TS2+ twin screw. (8.5 psi w/o cams.) The twin screw has been on there for 70k miles. This is my first time with a boosted car. It will see some track time when I am done with it. Need your guys help.

I knew the engine would come out and the lysholm unit / snout rebuilt. I also wanted to go over EVERY gasket and have a good baseline.

Lysholm snout has leak. I plan on having the snout / lysholm unit rebuilt. Who should I send it to? PSE, jon bond, ???

Replace or just rebuild injectors? who?

Would like a proper tune. Who?

Has a uuc lwf and Kevlar clutch. pedal is too heavy for my liking. options?

Lots more to come, but on to the pictures.

Welcome to the club!!

I wonder if Whipple (who owns Lysholm now) can rebuild it for you? Looks like the lysholm unit and the intake manifold could use a fresh powder coat job.

I'd suggest looking into the 42lb Bosch green giant injectors. According to some online calculators the 30lb injectors are at like 90%+ utilization, and I wanted more headroom. If you go that route you will want to upgrade the fuel pump too for good measure. I'm running the M3 pump, but you can use a walbro too.

And then if you have 42lb injectors, then I can help you with a proper tune. My tune would work fine for the normal red 30lb injectors but would need the global fuel correction and injector dead times (c_ti_as, c_ti_min, c_ti_add_dly) re-scaled/updated accordingly, which Frank Smith could handle for you.

I track my car too, its a ton of fun. The ATI damper is expensive but makes a real noticeable change in smoothness of the engine, I added it for a little more insurance/peace of mind since my car sees track duty. No doubt at 180k on your motor the stock damper is shot.

By the way, since you will be tracking the car, we definitely should talk tune. The ESS tune is terrible on the track. I've solved the throttle issue and now have smooth predictable control of the throttle again, essential on the track.

we should keep in touch. sounds like were on the same page.

ATI is definitely on my radar.
i had a fresh (only 2000 breakin miles) s50b32 sheer the crank key at gingerman.
i had an s54 blow a harmonics balancer at road america.
harmonics from high rpms can kill these motors.

assessing condition now and working out a game plan.

cheers, Jason

That’s a really big sc pulley.. :yikes:

Welcome to the TS family. You could upgrade to the Whipple 1.7 or even better the 2.3 :evil:

I was going to suggest Ryan for the tuning talk. :thumbup:

Welcome to the TS family.
Thanks! I guess i am part of the club now. How is your zhp project coming?

Eh, 79.5mm, is not THAT huge. But your right, it wont give me 18lbs like yours.

This should be good for my goals. pump gas, dual duty, inexpensive, reliable track toy. I know, I know.... no such thing as a good dual duty or inexpensive. I just need to get back onto the race track. And if i ball it up, i need to be able to walk away. (Will always keep the silver zhp for a daily.)

Cheers, Jason

I was wondering what size that pulley is, it looks like one of the early 83mm pullies ESS used to include in the kits. If memory is right, they are measured based on the OD of the high part of the belt grooves (on top of the grooves, not in between the grooves).

Not the 83. It was part of the ts2+ 8.5 kit. It does measure 79.5mm with the micrometer from the high point of the ribs.

When I first got the car, it showed 11+ psi on the top end. (Tough to believe.). Pressure readings are post screws, but pre intercooler. As it turns out, the laminova cores look clogged. So, those are coming apart for a good cleaning too.

Which reminds me, add “catch can” to the list. Does anyone make a catch can that self drains back to the stock dipstick line? Had an ls2 e30m3 thatt needed a catch can. track side maintenance (constantly draining it) was a pain. Looking to simplify.

Thanks. J

I'm using manual draining catch can (sorry, it's in Russian) but I get quite little liquid there (and mostly in cold weather), so I don't think that auto-drain catch can is really required with that setup.

Went with the Mann Provent 200.

Sorry for the delay.

Yes. Engine is in. Need to do some plumbing. I found the ess hose rubbed through and the intercooler out of fluid. The pump was pushing air.

Now I’m rerouting to my liking ( think swirl pot) where you can easily check that there is fluid moving. Using the drug bin and running all new lines. It’s done except for the intake. ...and need to put bumper on.

Housing issues (and running a small business... and being a father) has taken priority. Will post update shortly. J

You're getting there, keep us posted, this sounds fun. I'm excited for you to get it on the road! And I hope you'll join me at Gingerman or Gratton this year sometime! I just picked up a set of Schricks so I'll finally be TS2+ sometime this summer. I'll keep my same 79mm pulley so that means boost should drop a PSI or so while making more power, so I hope that translates to slightly lower temps at the track. Running 11psi (pre cores, with 79mm pulley) has me a little worried about heat. On a 92 degree day last summer the car did get a bit hot after 3-4 hard laps. If it drops to 10psi then maybe that helps keep things a little cooler on those super hot days.

making progress. All buttoned up. Need to flash and get an alignment.


Thought i would share my intercooler swirl pot. After taking the engine out, i found a failure in the intercooler hose. The system had been run dry and there was no coolant remaining. My solution was to make a clear swirl pot. It gave me the benifit of always being purged and I could visually check the system.

cool idea with clear tank but bad idea with a pump located so high. it should be in the lowest point.

Thanks. But I respectfully disagree. Pump doesn’t need to be lowest in system. Pump is directly below the surge tank. That’s the whole idea behind a surge tank.... you eliminate potential of drawing air.

We are all going to have air pockets. I will have the air trapped in the surge tank in lieu of air in the cooling system lines. The stock ESS system will have air trapped somewhere in the cooling system, that’s why you should keep yours mounted low.

yep, I agree, it will work when you have some coolant in the tank, but in the lowest point it will work even when the tank is empty but you have some coolant in the hose. on the other side, when the pump is located low with long hose from the tank, it's harder to bleed the system, so anyways I love your setup. can't do the same since I already have methanol there, and also my ess coolant pump is much larger then yours :) so I located it in bumper and added a tank near the throttle body connected with T-connection. not as perfect as yours go-through tank but it works almost the same

Very cool, nice work Jason!
Thanks. Took it around the block yesterday. Getting alignment Monday.

Here***8217;s something weird.....
I CANT DRIVE IT! Car will NOT allow heel toe!
One touch of the brake and the throttle cuts off.
How can anyone downshift?
Is this an ESS thing?

rkneeshaw, Your tune is going in this weekend!
