Okay, I read many posts on this subject, however can anyone recommend or oppose any blockguards (brands as well) from personal experience.

many thanks

I have a race engineering blockguard on my LS, no cooling problems.

the raceeng.com ones are nice. They dont have much problems from what i hear.

9psiLsT are you running a stock radiator?

LsTurbo91

yes stock cooling except for a 160 degree thermostat.

really? I've seen 2 of 5 I've used crack (the guards and the block) - both were on LS's.

LsTurbo91

yup. The only cooling problem I've had was when I switch my stock gutted fan to a slim autozone fan. The temp would rise if i was stuck in traffic then if i get moving again it would drop back down. So for now I have to leave it running all the time if its like 100 degrees outside other than that its fine.

Vaportrail: How long after you installed the blockguards on the ls's did it crack, how much were they boostin?

bruthaboost

Also what do you think caused the cracking?

Well heres my experience:

Got the STR blockguard for my LS. Finally got boosted a couple of weeks ago.
I talked to the guy that helped me install my turbo and he asked me if I put the blockguard in before I machined the cylinder walls....nope. I don't know what cylinders if not all 4 are warped. She smokes like a bitch now...sad sad days until I get it fixed. And its all my fault.

This is my experience with building my motor. Some have never had a problem so weigh your options.

i have heard of numerous blocks getting warped from the str blockguard... imo i wouldnt trust it...

bruthaboost

Thanks for the experiences and advice y'all. I'll stay away from them and on the conservative side of boost

at what psi level is a block-gaurd recommended ?
