Wheels
OEM for now wearing Continental contact 3. Upgrading to Advan RS 17x8.5 wearing 245/40/17 Michelin Pilot Sport 4.

The run was done in 3rd Gear, 93oct pump gas. The boost was 25psi and uptop dropping to 20psi probably due to backpressure issues. I also attach the csv file of the log.

Next step after the purchase of Magnus V5 and S90 TB, is the purchase of a T4 1.15a/r 6466 TS with a T4 TS Manifold and twin mvs 38mm wastegates. After these, I will try to hit my goal which is around 600+whp or even 650+ on pump gas. Before you ask me why I use pump gas, E85 is unavailable at my country and race gas is not in my thoughts at the moment as it is a DD. However, here we use 98oct RON pump gas which i think it is a high quality 93pump gas in us

Thank you

 

i notice you had 4.11 final. you did correct your VD data for it .. correct?

 

Needs more wgate preload. tq is delayed badly.

 

why are you not seeing full boost until almost 5k RPM?

 

Yes, i corrected it

 

That is what i noticed too. The wastegate is a Forge IWG with a 18psi spring

 

I do not know what is wrong with boost. I attached the csv log file. i did not manage to set up virtual dyno to show psi correctly. I maybe doing something wrong with the log recording

 

Keep in mind that the tuning was done on the street and not on dyno. I do not know if on dyno the tuner can set it up to spool earlier

 

Something isn't right. A 20g on a 2.4 should see peak boost much, much sooner.

 

I know. I will have a look to my wastegate preload and also on my 10.5 hotside for possible leaks

 

I'm not too familiar with a 20g, but my FP HTA71 reached 20psi by 3400RPM or so and my FP Green did so around 3600RPM, both on a stock 2.0L. You're not seeing it until 4300RPM. Could be a number of reasons, but I'd do a boost leak test just in case, so you don't kill the turbo.

 

Update.

This weekend I tried to adjust the wastegate preload. the preload was far too stiff. Maybe 6 full turns. I adjusted it to 3 full turns and took it for a road test. It seems that it had slightly better spool but nowhere near from what is supposed to spool. Probably the hotside must have cracks. Here's the new log

If I may make a suggestion if your going new intake mani, look at something with larger runners to let that 2.4 breath. The magnus is a sweet piece but to small for the 2.4. I would suggest the AMS f1 if you could fine one, or a JMF manifold. The larger ports on the runners will help a ton. Plus it will push the rpm band more to the right some which will help your top end. I am planning on running a JMF drag mani on my car. Good luck with the build.

 

Your spool is bad. My 2.4LR (gsc s3+ magnus V5+fp black mhi housing) hits 300tq sooner than yours. Is your 2.4LR cam timing spot on?

 

Remember he is on a stock intake mani, and tb they are both choke points on a 2.4. My car makes 300 ft lbs of tq by 3500 rpms on stock tb and Rev3 ported intake mani with a turbo similar to a black.
