Default TIC's New TGV's. They Really Do Work.

Been a busy busy past couple of weeks moving and setting up shop, but finally got a chance to finish testing TIC's new composite TGV's. Couple of notes. Some may have slight fitment issues with the IM bolt holes. I have the solution that does not require slotting the IM. Leave the TGV's slightly loose and get the IM/TGV's lined up and bolted, then tighten the TGV's to the heads. Anyways moving on:




I beat these things to death and tested out the temperatures at the TGV's and at the IM runners. I was pretty surprised to see that they on average reduced the TGV and IM temps by 10*! This is WITH thick phenolic spaces on as well (both stock and TIC's). Here are the results.

Stock with Phenolics:
At TGV's inner side is where the temps were measured:

#3 - 145* #4 - 140*
#1 - 141* #2 - 141*

Note: #3 is hottest due to location by turbo.

Intake Manifold @ the runners above flange

#3 - 124* #4 - 111*
#1 - 128* #2 - 119*

TIC's Composite TGV's:
@ TGV's

#3 - 140* #4 - 105*
#1 - 130* #2 - 130*

Intake Manifold:

#3 - 110* #4 - 102*
#1 - 113* #2 - 109*

Nice! Ive thought about this exact thing back when folks were talking about how cool there composite 08+ wrx, 05+lgt etc.

Great to see some real world proof.

Thanks Crystal, and Thanks TiC!!!!!!

Have you seen any whp gains?

I haven't install mine yet but I am going to install them phenolic spacer with the TIC TGVs.

Here is my stock TGV readings with 3mm phenolic spacers for reference, cylinder #2:






I can't wait

hmm, how well do they work without phenolic spacers compared to stock, and compared to them with the spacers?

They look purty.
What's the design benefit over the Cosworth TGV?

I cannot test without spacers as my reverse im will not clear without spacers. I am sure it will still help greatly.

As far as compared to cosworth i would guess price is the major difference.

I know this request is unlikely but i would REALLY like to see these tgv's with an option with secondary injectors like the old aps tgv's.

One last thing for anyone that has a setup like mine. If you had your grounds on your tgv's you will need to run an extension of your harness to ground on your intake manifold or etc.

I thought the main point of these was the TGV delete and not the temperatures.

Yes it is and it also so happens that they perform the same task as spacers insulating the IM. You can only port them so much, flow from a metal one to these wont be much different.

What is your main point?

This is the review I was waiting for! Thanks

I'm sure more ideas would be out of the question but I would really love to see +8mm TGV's for reversed mani's. Want to reduce/remove as many steps or failure points as possible lol.

Also, your "setting up shop"? : )

The only reason I'm skeptical is because with these composite materials, if you over-torque by even the slightest amount, crack, they are now garbage.

The inserts are quite strong and would probably pull out a little before you cracked it. Besides that, this type of polymer is very strong and it would take some force to hurt it.

Absolutely. I'm hoping that TiC will include exact torque specs in order to prevent over torquing. Even so, in the past on one of my older honda's I installed the Skunk2 composite fuel rail, followed their torque specs exactly and they still cracked.

It wont take much to compress an o-ring. I cant speak for TiC but I would guess they have though of this and will provide some guidance for people who are unsure. I know Greg loves answering the phones too so you can always give them a call if you wanted or had questions.
