Default 20G owners that track their cars

I've heard some say that the turbo is too laggy for tracking and doesn't spool quite fast enough in the turns. Is that the case?? I thought DBs and SBRs only spooled a few hundred RPMs slower than the vf39.

I've been considering getting a 20G, but I also want to track the car about 2 to 3 times a year.

What's everybodys thoughts on the 20G and the track? Too big or?

Thanks -

Too laggy?? The 20g on my car is no laggier than the VF39 when i had it stock. My experience is just doing DE's.


I actually just came back from the track(Limerock, CT) and did many a track day with the 20g this year. The thing is a track monster. It is extremely responsive and throws you back into the seat pretty much immediately. I couldn't be happier with my setup for the track in terms of power at this moment. It is very tractable, powerful, responsive, and FUN as anything i've ever experienced. It doesn't die off in the top of the rev range like the VF39 does and builds boost just as quickly. I'd say it's the perfect track day turbo upgrade. Lagginess, responsiveness, and tractability also has a ton to do with the tune. If it's not tuned right, it could feel like a pig.

My setup:
DB Td06-20g internally gated
PE850cc inj
walbro 255
Spearco TMIC
TurboXS stealthback(SwainTech coated DP) w/ highflow cat
prodrive axelback
Perrin UP(ST coated)
Perrin drop-in filter
UTEC tuned by TurboXS

I think that's everything. i can never remember,

edit: forgot one thing, Perrin EBCS

edit: forgot couple more things. Swaintech coated my stock exhaust manifolds and heat sheild as well,

Just got mine and based on driving the setup a couple of weeks, I think I will enjoy it a lot more on the track than a tuned VF39. The VF39 is fantastic on the street but the RPM range I usually find my self in on the track is 3500+. I found the VF even on race gas falling off big time in the high R's. The 20g just keeps pulling and pulling and pulling. Worst case would be you'd have to downshift a little more on slow corners. Honestly, once you get used to the powerband, you love it.

wow, thanks for the replies guys. I feel A LOT better now.

Gills, what kind of numbers are you putting down on the dyno with that setup? I have a catted dp as well.

ChrisF - thanks for the input. I've heard that about downshifting as well, but it sounds like everything works out well though!

I'm thinking either SBR 20G or DB 20G at this point.

The SBR 20G is going to spool a few hundred RPM slower than say the FP or DB ones, but will give more top end power. On a track having a laggier turbo is less of an issue if you are all about maximizing speed in the straight portions. Having a more responsive turbo may be more fun though.

JM,

I put down 335whp and the same of torque on TurboXS's dyno on 93 octane in very hot weather. I also have the highflow midcat which is a little bit of a plug. My downpipe is cat-less. Not sure if you misunderstood.

Jermaine from TXS told me that i could free up a couple extra ponies by going completely catless and getting a straighter through axelback, but that is neglible to me. I don't even run that map when i'm tracking it because it's not necessary at a DE.

As for extra downshifting, it's not even necessary, trust me. Keep it in the higher gear, hit the apex correctly, roll on the throttle a little earlier and it pulls like mad.

Thanks for the info, Gills. I gotcha on the dp/mid cat stuff. How is your top end on the DB? Also, what is DE?

DWX - That's what I hear about the SBR. The plots for it are incredible as far as mid and top range. I am somewhat torn between the SBR and the DB because of the slower spool of the SBR, but the top end is gigantic. The DB on the other hand seems to spool faster, but is not as strong up top.

DE= driving event. Short for HPDE- high performance driving event. Just another nomenclature for track day.

The topend on the DB is very good, but if you want that extra pull up top get the SBR

Did you notice a difference switching from the stock axle-back to the Prodrive unit?

I already had the prodrive exhaust installed when i got tuned so i dont know if there was a difference. Jermaine said a max of 5-7hp from the prodrive over stock and that makes sense. It`s not that much freer flowing that stock but surely offers a huge improvement in sound!!
