Have a car and didnt know it didnt have these basic 3 mods.

Its an OEM 10.5 hotside turbo but lags a little because of this.

With these basic mods how much better spool and whp should I see?

Car has cams, meth and cat back only.

Also has the OEM Intake box.

 

I would recommend a walboro 255 and a boost controller along with those mods to get maximum results

 

zero

 

I have these mods and dont see any faster spool up.

 

Car has walbro 400, cams and meth

 

If you want really people to help you, you should start by providing them with all the information that you have. For starters a complete mod list, in one place, like my sig. makes things a lot faster and easier for everyone. A quick story of your history with the car will help, also.

 

10.5 hotside OEM Turbo
R2 Cams
Meth kit
3" Catback
Hallman


Car had 340 whp and boosting 28 PSI

Tuner says though lack of down pipe, test pipe and intake is hurting a little and o2 dump would help a little

 

These ar called basic bolt ons,so either way you need to have it. External dump is optional but ppl see extra ponies.will it help to improve spool up or not hard to say but it will extract more power for sure.

 

When I went to short route hardpipes, and a full turboback I saw a very noticeable 500rpm earlier spool. Makes the car much more enjoyable to drive.

 

i had dump on stock turbo for a long time, there wasnt a noticable spool difference..stock spools so fast anyways lol..it did help with making a little more power and tq..mostly tq...and is loud if u like more noise..and if u have a cat replacing it with a test pipe will defenitily open up more power..just will throw tune off..so need to adjust it.
